CRM -

12:00 AM is midnight, which is 0 time. Depending on how you get your time,
you might just need to test for E9=0, like this:

=IF(E9=0,(E9-D9)*1440/60,"")

Check for negative hours (depends on how you have the time). If you get
them, then you will need to add 24 hours to the negative amount.

I am sure this question has been answered before but I am dizzy trying to
sort through all of the other posts when I run a search.

I have a spreadsheet that does some pretty basic time in and time outs. I
have a validation table only allowing time on the quarter of an hour for the
time in and time out. It is formatted in 12:00 AM time.

In this particular instance I cannot get my formula to work when the end
time is 12:00 AM. E.g.:

Start time (D9) is 10:00 PM, End time (E9) is 12:00 AM. My formula reads
=IF(E90,(E9-D9)*1440/60,""). This formula returns nothing when the end time
is 12:00 AM. I need it to return 2.00 for the amount of hours.

Any thoughts and Thanks!
