Auto-fill the date in a cell, when the user enters information in an adjacent cell

Question

I have a spread sheet, where people can enter project updates and then the date of the update. What is happening is that people are forgetting to date their notes. Is there

Answer 1

Try this formula in the desired cell (e.g C13) to fill the current date when corresponding input cell (e.g D13) is not empty and not filled with 0 :

=IF(AND(D13<>"";D13<>0);TODAY();"")

And then you can copy this formula to the subsequent cells to fill in the formulas for that column (e.g col C)
