User input if cell not completed

#1

Hi All,
Apologies if this has already been covered but I couldn’t seem to find anything.

Question:
Is it possible, on a button click, to prompt the user to enter a value or to warn them that a cell is blank and needs to be completed?

Context:
Creating an internal task app for my team and I need them to enter the time they have spent on each task when they mark it complete (via the complete button). They always forget to enter the time and hence I wanted a way to verify the time value and warn if not entered (or preferred, popup so the user can enter a value) before they can mark the task complete.

Thanks
VTL

I don’t know the details of your table, but would it be possible to disable the button if the time column is blank?

Then they would have to enter a time before they could click submit.
