I have a form that I would like to calculate the time taken since the last input was made. We have a vessel that fills between either two days or sometimes a week. I have a field to input the time the vessel was full and would like to have the "time taken to fill" field to update. I have very limited experience with access.
Please let me know if you require more info
Regards
Bob
