Is there anyway in excel, if a user enters a value in a cell, i.e. 4, it automatically performs a calculation to change that value. For example in A1, if a user types 4, in cell B1 I have the value 4 pre-populated, so I want A1 to show the output of the formula
so if the user types 4, it will return 16. I cant see anyway to do this via formatting.
