I created a spreadsheet, designed for payroll scheduling. I've received no formal training in excel, have learned everything I do know through trial and error and internet searches. I will list the series of formulas in generic cell pattern and describe formatting to the best of my ability. Unfortunately, I don't have a home computer at the moment and this worksheet is on my work computer, so I don't have specific codes at the moment. Here goes...(A1,A2) input number in "military" time format. (A3,A4) convert (A1,A2) values to display actual time in hh:mm. (B1) =sum(A3-A4)converted to numeric decimal (B2) recognizes a greater than number value in(B1) as true. (B3) converts true value in (B2) to ".5" and if "false displays "0".(B4)=Sum(B3-B1). (C1)=(B4). (C2)converts (B2) value to "L". I hope that makes sense to you. The problem I have is (A1,A2) carries the potential of being empty, if (A1,A2) are blank (A3,A4) display #VALUE! Error Symbol and causes the formulas in (B1)(C1)(B4). I've tried the recommended IFERROR,ERROR_TYPE,REPLACE,REPLACEIF,CONVERT, CONVERTIF AND CONDITIONAL FORMATTING formula settings. I can get(A3,A4) to display 12:00am but still interferes with (B1,C1,B4) formula displays.I don't know if I'm using them correctly or In the right order or if the formulas I obtained are correct. PLEASE HELP!!!! I would need a layman's version of the correct formulas and steps to fix this. Thank you in advance for any and all help.
