I have a Smartsheet that is being used to login dates as an item is processed through various steps until completion. I would like to create a column that automatically shows what step in the process the item is on. I can do this by combining if/then formulas, but there are at least 15 steps and I am hoping there might be a better way to create the formula.
Sample
Column A Column B Column C Column D
Shows a Date Shows a Date No Date Showing No Date Showing
I want the formula to automatically tell me that Column C is where the item is in the process. Then, when a date is added to column to column C, it will show column D.
