Happy Thursday.
I know many have asked this question before, but does anyone know of a way to have a column actively countdown time? Even if a plugin is needed, it will be considered. Here is what I'm looking to do. When a form is filled out and a new line is added to the sheet, I'd like the "Countdown Timer" column to begin counting down that time to zero. In my example below, the end time would be 14:30. The timer column would need to count down to zero and stop when 14:30 is reached.
Any help is greatly appreciated.
Thank you in advance.
