Libby,

When Excel displays times, it displays them as "time-of-day"
times, always between 00:00:00 and 23:59:59. The square brackets
[] indicate to Excel not to "roll over" the time at 24:00:00, so
a time of 36 hours, 30 minutes is displayed as 36:30 rather than
12:30.

Yay thanks Chip!

I'd left out the []
How do they change the outcome though?

Libby,

What number format are you using in the result cell. It
should be
formatted as [hh]:mm:ss including the [] characters.

I still can't get it to work

I've got 12/12/2003 09:00 in once cell and 11/12/2003
09:00 in the other
When I take the second away from the first I get
00:00:00
when it should tell me that 24 hrs has elapsed.
