Hi again everyone....
I am currently using the following custom format:
[h]:mm
How can I use data validation to prevent invalid
data from being entered into a cell of that format??
For my purposes, I only want data which consists
of 1 or more digits in the "hours" field, folowed by
one colon, followed by 1 to 2 digits in the minutes
field.
Do I need to enter some sort of formula into the
data validation field??
thank you!
