If after doing a sum cell A1 = any figure between 30.01&40 I want cell B1 to automatically become 2%
If after doing a sum cell A1 = any figure between 30.01&40 I want cell B1 to automatically become 2%
This requires two separate steps.
=IF(AND($A1>30,$A1<=40),2%,0)
0%;;
The cell formula will either write 0 or 0.02 to the cell. This is important to know in case you wish to do calculations with this result.
The cell format willl change the value of 0.02 into 2% and hide the zero. Zero is better than "" because it is a number. If you wish to show it, remove the two semicolons from the formatting mask. The other part of the mask ("2%") determines the format of the number. You could make this "0 %" (with a space) or "0.0%" (with a decimal digit) or any other valid number format.
