I would like to put a value to A1 and when I changed A1 I want to keep the first entered value in another cell.
Would that be possible ?
Thanks
Here is a solution using formulas, only. It requires that you switch the iterative calculations on in Excel options. You can set it to 1 iteration.
You only need to enter the following formula into B1:
=IF(ISBLANK(C1),IF(ISBLANK(A1),B1,IF(B1="",A1,B1)),"")
A1 is the cell whose value is to be remembered, B1 is the memory location, C1 is the reset button.
