Using "control shift colon ( : )" a time stamp can be put in a cell. I want to add a time stamp every time a drop-down menu option is chosen. Can anyone please help me with a method for doing this? Some additional context: I want to have two columns - call col A the drop-down menu column and col B the time stamp col. I will select from col A at different times throughout a session. Indeed - it is possible that I will have several sets of col A and col B on the same worksheet.
