Format ALL your time cells as [hh]:mm, not only the grand total, and you
will hopefully spot the problem.

Hi,

I have the following info in an excel spreadsheet:

Starttime EndTime Hours SubTotal
8:00 am 9:00 am 1:00
12:30 pm 2:30 pm 2:00
3:00


I am adding all the cells in the Subtotal Column and my grand total is
24
hours...something like 27:30. I used the formula =sum(D1:D34) on the
Grand
total field on Column D and formatted the cell as [hh]:m following the
advice
in this discussion forum.

My total is still not coming to 27:30. It shows up as 314:30. What am I
doing wrong? Can someone help me please?
