Use a custom format for the total cell:

[h]:mm

will stop hours above 25 being treated as days.

The same can be accomplished by choosing the format "37:30:55" from the
list provided under Format | Cells | Number (tab) | Time.

Hope this helps.

Hi,
I need to add up a list of hour and minutes, the only problem being is that
Excel treats them as TIME not hours and minutes.

For example, if I sum 7:24, 7:24 , 7:24, 7:24 [ where 7 = hours and 24 =
minutes ] then Excel five me an answer of 05:36 rather than 29.36 - any ideas
how I get this working ?

Thanks
