Presumably you'd be entering N, lambda, D_1 and D_2, and want F_N. If so,
calculate F_N as
=SQRT(N*lambda*HARMEAN(D_1,D_2))

I'd need to edit this site's source to find the formulas in the php code.
You wouldn't happen to have a more explicit reference, would you?

Again I need help with the formulas. I could use these but I need them

I know how to ste the name fields and have an area for the value to be

All,
If anyone can help with this, they are a legend. It will save me so much time.
My boss wants me to use the Westbay call centre calculator (http://www.erlang.com/calculator/call/) as they believe this is the most accurate when working out how many agents we need. However, plugging figures in to this calculator is tedious and not time effective (you can tell I work in a call centre), especially when using massive amounts of data.
I have downloaded Erlang C for Excel and I have used the example document which comes in the .zip file. To make this explanation easier I have made a few tweaks to make look it look similar the Westbay calculator in format.
Now to my problem. When figures are plugged in to both calculators the number of agents does not match.
Westbay Calculator
Excel Calculator
Any idea why this is and what I can do to make them match?
Ideally I would like the Excel document to return the exact same figures as the Westbay tool.
Many thanks,
Lee.
Hi all,
The yield function in excel does not give the right value if I play around with the redemption value(% of par). I have checked this with other available online bond yield calculators such as
http://www.moneychimp.com/calculator...e=calc_bondytm
If I change the redemption value to 50 and the bond price to $50, ideally the coupon rate and the yield should be equal for any time period. While this happens in the calculator mentioned above, Excel gives me a different number. Is this actually a bug or am I missing the point?
Test this in Excel...
=YIELD("6/30/2009","6/30/2022",0.0958,50,50,2,0)
Also test different redemption and price values and compare them with the calculator above.

Hi. First post here, looks like a good place for Excel info.
I'm not really familiar with Excel's iteration and how to set it up properly. Here's an example of a problem that requires iteration:
1 / λ1/2 = 2 log [ 2.51 / (Re λ1/2) + (k / dh) / 3.72 ]
Only one value of lambda (λ) will allow the two equations above to be equal, I need to balance the equations and solve for Lambda. The way I do this now is using VBA (code below)... can this be done without VBA using only Excel and iteration? If so a detailed explanation (using the example above) would be much appreciated.
VBA code to solve above:
Code:
Public Function GetFrictionFactor(rgRe As Range, rgK As Range, rgDh As Range) As Double
Dim Eqn1 As Double, Eqn2 As Double
Dim Lambda As Double
Dim Increment As Double, Tolerance As Double
Lambda = 0.0001
Increment = 0.000001
Tolerance = 0.00005
Do
Eqn1 = 2 * Log(2.51 / (rgRe.Value * (Lambda ^ 0.5)) + (rgK.Value / rgDh.Value) / 3.72) / Log(10)
Eqn2 = 1 / (Lambda ^ 0.5)
If Eqn2  Eqn1
OK, I know that you can use scripts to call calculators such as the following.
Code:
Sub OpCalc_Click()
'Standard Module code!
On Error GoTo Err_OpCalc_Click
ActiveSheet.Select
'Open the Calculator!
Call Shell("Calc.exe", 1)
Exit_OpCalc_Click:
Exit Sub
Err_OpCalc_Click:
MsgBox Err.Description
Resume Exit_OpCalc_Click
End Sub
However, I would like to make my own userform calculator so that I can modify the way it looks, size, font etc... and can add in other things if need be.
Does someone have a worbook that they can provide that has the scripts for a userform calculator that I can then modify the look etc.... to suite my desires.
I have searched the net but haven't found anything worth while.
Thanks
I'm trying to set up a report that calculates fees in order to validate fee
calculations on another system. Column one contains a reference to a fee
schedule; i.e. schedule A, schedule B etc. Column 2 contains the account
value. So I need to look up the appropriate schedule, use the appropriate
calculator and return the result into column 3. Part of my problem is that
the fee calculators are not in a single cell, although I could probably
rewrite them if I have to. (The fee calculators discount for higher
balances i.e. 1.00% of the first $500,00, .85% of the next $500,000, .75% of
the next $1,000,000, etc) Any ideas and/or formatting suggestions would be
appreciated!
I have an Excel 2003 spreadsheet used to calculate doses of medication. The value of several cells will depend on what optionbuttons the user selects.
I have entered the first two lines of code below w/o a problem to make certain calculations that are displayed in the specified cells. I then tried to make an additional calculation to display in cell 6,9, but it always triggers a "Applicationdefined or objectdefined error". For troubleshooting purposes, I moved that line of code directly under the other two lines of similar code that I know work, and simplified the problem line to just arbitrarily set the value of the cell to a value of 2 (instead of the actual formula); it still triggers the error.
Code:
'CVM Pharmacy Protocol
Worksheets("CRI CALCULATOR").Cells(16, 3).Value = Worksheets("CRI CALCULATOR").Cells(5, 8).Value / ((Worksheets("CRI CALCULATOR").Cells(15, 3).Value * Worksheets("CRI CALCULATOR").Cells(3, 8).Value) / Worksheets("CRI CALCULATOR").Cells(10, 3).Value)
Worksheets("CRI CALCULATOR").Cells(16, 8).Value = ((Worksheets("CRI CALCULATOR").Cells(5, 8).Value / Worksheets("CRI CALCULATOR").Cells(17, 8).Value) * Worksheets("CRI CALCULATOR").Cells(10, 3).Value) / Worksheets("CRI CALCULATOR").Cells(3, 8).Value
Worksheets("CRI CALCULATOR").Cells(6, 9).Value = 2
I really would appreciate insight as to why this simple change in a cell value is triggering an error. I've attached the file. To trigger the error, pull up the worksheet "CRI Calculator" and click on either of the optionbuttons with blue text, or doubleclick on a name in the listbox. The worksheet is protected but it has no password, so it should unprotect easily. Thanks!
Hi
I have a mesh of Networking equipment in my office and we have an excel sheet maintaining the interconnectivity of the routers
Near End Far End
Router6 Router5
Router7 Router5
Router5 Router3
Router3 Router4
Router3 Router1
Router1 Router2
Gateway Router1
Now as you can see the arrangement of "Near End" and "Far End" is totally arbitrary. The actual connectivity is as follows
Gateway
/
/
/
Router1
/ \
/ \
/ \
Router3 Router2
/ \
/ \
/ \
Router4 Router5
/ \
/ \
/ \
Router6 Router7
I wish to make a macro that can give me the appropriate "Far End" that connects the node to the gateway. For example given Router3 the correct "Far End" would be Router1. The End Result of this macro would be something like this:
Near End Far End
Router6 Router5
Router7 Router5
Router5 Router3
Router3 Router1
Router4 Router3
Router2 Router1
Router1 Gateway
Any help is highly appreciated.
I have recently made a calculator with UserForm (in Excel 2003) and would like to convert it to an Addin to distribute to my colleagues. I've read several references as well as a link posted in this forum but still cannot get it save properly.
Most instructions say to start with a new empty workbook but I've already put in a lot of time with this calculator and don't want to remake the userform. The references say I need to add a Toolbar.
I understand the need to unload the toolbar when exiting and some of the concepts but I'm having trouble saving as .xla file.
I've put the following into This Workbook
Private Sub Workbook_BeforeClose()
Toolbars("Calculators").Visible = False
End Sub
Private Sub Workbook_Open()
Toolbars("Calculators").Visible = True
End Sub
When I go to compile I get the following error message that I don't understand.
"Compile error:
Procedure declaration does not match description of event or procedure having the same name"
It then highlights the first Private Sub Workbook_BeforeClose() line. (The info after the help button wasn't helpful to me.)
I took this straight from a book and followed the multiple steps.
Thanks,
Philro
Thanks very much Ron  That'll work just fine.

Shaun C.

I am trying to create my own dutching calculator but I have become stuck.
Here is an online dutching calculator:
http://www.ukhorseracing.co.uk/tools...Calculator.asp
I also have this one (attached file) but it is locked, so I cannot edit it. I can't even understand how it works as the formula refers to empty cells.
Thanks in advance.
Dan
Instead of having to pull up the calculator off the start menu then transfer
that data to excel, it would be great if we could have a way to calculate
within the cell we want the data.

Hi, I'm trying to set up a direct link to the internal excel calculator, using a button in VBA.
I have the shortcut on my own toolbar, but I have many users that use the workbook, and to get them all to set up is almost impossible, so I am trying to make it simple for them.
I've tried doing it through a hyperlink direct to the calc.exe file, but get a lot of messages popping up (that'll scare a few of them).
So thought I would try and find the excel name for it and use VBA, but I cannot find it anywhere.
Can anyone help ?.
Basicaly the only formula I can use is the if formula but everytime I use it it ends up looking like a mess and the fomulas cause me a headache when I convert it to earlier excel programs
=IF('Cookie Calculator'!$B$3=Sheet1!$B$3,Sheet1!$M4,IF('Cookie Calculator'!$B$3=Sheet1!$C$3,Sheet1!$N4,IF('Cookie Calculator'!$B$3=Sheet1!$D$3,Sheet1!$O4,IF('Cookie Calculator'!$B$3=Sheet1!$E$3,Sheet1!$P4,IF('Cookie Calculator'!$B$3=Sheet1!$F$3,Sheet1!$Q4,IF('Cookie Calculator'!$B$3=Sheet1!$G$3,Sheet1!$R4,IF('Cookie Calculator'!$B$3=Sheet1!$H$3,Sheet1!$S4)))))))+3
Ive even broken some of these formulas up for when there are 2 reference,
=IF($B$1=Sheet1!$A$4,Sheet1!X4$C5,IF($B$1=Sheet1!$A$5,Sheet1!X8$C5,IF($B$1=Sheet1!$A$6,Sheet1!X12$C5,IF($B$1=Sheet1!$A$7,Sheet1!X16$C5,IF($B$1=Sheet1!$A$8,Sheet1!X20$C5,IF($B$1=Sheet1!$A$9,Sheet1!X24$C5,IF($B$1=Sheet1!$A$10,Sheet1!X28$C5,IF($B$1=Sheet1!$A$11,Sheet1!X32$C5,IF($B$1=Sheet1!$A$12,Sheet1!X36$C5,IF($B$1=Sheet1!$A$13,Sheet1!X40$C5,IF($B$1=Sheet1!$A$14,Sheet1!X44$C5,IF($B$1=Sheet1!$A$15,Sheet1!X48$C5,IF($B$1=Sheet1!$A$16,Sheet1!X52$C5,IF($B$1=Sheet1!$A$17,Sheet1!X56$C5,IF($B$1=Sheet1!$A$18,Sheet1!X60$C5,IF($B$1=Sheet1!$A$19,Sheet1!X64$C5))))))))))))))))
As you can see this is starting to become a bit of a mess, could someone tell me where I can go to learn about formulas in english so I know which one to use and when.
I have attached a worksheet so you can see how I make a simple thing turn into a big episode due to not understanding what formula to use where.
Hello,
I am trying to set up a Calculator which results in the Number of Roof Tiles I need for a House construction.
Most of the Calculators I have found are imperial but I need metric.
Does anyone have any ideas please
Thanks
Barry
I have attached an example
I have a spreadsheet where my calculation ( results ) should be the same as if you were to calculate the same input as on a calculator.
Example :
Cell A = .351
Cell B = 9.444
Cell C = 34.444
When I use the following formula : A / B*C = 1.28011 is my answer
When I calculate the same thing on a calculator my result is 1.28055
This gives me a variance of 0.044% which I cannot "use" because this can cause an incremental increase which I cannot allow for my calculations.
Is there any advice or guidance that anyone can give to help me with this? I basically need my numbers to "match" what will calc out on a calculator for those who do not have access to Excel. Thanks in advance.
I have found a on line calculator. What formula I have to use in excel to get the same result?
Current age:30
Monthly pension required from age 60 (Rs.) 5000
Growth rate per anum 10
The answers comes as :
Annual premium payable till age 60 (Rs.) 7,267
Retirement fund available at age 60 (Rs.) 817,381
Link for the calculator is:

Hi all,
Ajay if you are able to assist me with this I would be most greatful, since you have the history with this spreadsheet. I will attach it again, but this time I need the program to function off of the "AFTERNOON *** CALCULATOR". I tried copying the program from the "MORNING *** CALCULATOR" into this worksheet, and changed "MORNING" to "AFTERNOON" in the code, but it does not work. I need it to look at the date (which is tomorrows date in the afternoon calculator. cell O24) and add the corresponding value in column F of the "*** LOG SHEET"
this is the thread with all of the history from the first time around
http://www.excelforum.com/excelprog...dependant.html
I need to find a way to have Excel find a link and click on the link in Internet Explorer.
The link name is unique in the page, and the href looks something like this.
HTML Code:
<A HREF="http://www.somelink.com" target="_report" *******="click=1;">Some Link</A>
Thanks!
I tried searching through the forum to find a solution to this, but I found none that fit exactly. Granted I didn't check each of the 400+ thread. SO I apologize in advance if this has been covered.
Okay attached is an example of the timesheet that I am working with. I have tried a bunch of formulas that worked for the most part, but then one thing wouldn't one. So I decided to ask for help.
On the worksheet, you will see that there is 2 workbooks, Time Calculator and Employee 1. Here the thing. I need 'Employee 1"!C8 to = 'Time Calculator'!O5 if it is under 40 hrs. If the sum of 'Time Calculator'!M5 and 'Time Calculator'!O5 > 40 hours, 'Employee 1'!C8 needs to show the amount of hours used to equal 40 hours and then put the rest in 'Employee 1'!C9 (o/t).
ex.
Time Calculator M5= 21 hrs
Time Calculator O5= 21 hrs
Time Calculator Q5= 15 hrs
Employee 1 B8 should = 21 hrs
Employee 1 C8 should = 19 hrs and Employee 1 C9 = 2 hrs
Employee 1 D8 should = 0 hrs and Employee 1 D9=15 hrs
If you need further explaining, just ask. Thanks for your expert help in advance.
