I have tried to formulate a cell (e.g. A2) as it can be summed iteratively by another cell value (e.g. A1) when A1 is updated. The following formula is used using some previous SO answers:
=IF(A1<>"", IF(Total="", A1, Total+A1), "")
In which "Total" is referring to A2, and iterative calculation is enabled in formula option by maximum iterations = 1.
The solution must be as e.g. if A1 = 2 then A2 = 2. Then if cell A1 be updated to value = 5, then A2 becomes equal to previous A2 value + new A1 value
i.e. = 7.
The issue is that when I am using this code, each operations on each other cells execute this code e.g. if A1 = 2, so A2 = 2 but placing a value in B20 (no matter which value) execute the code and A2 will be changed to 4 (2+2).
Is it possible to formulate the cumulative sum without VBA?
