[h]:mm will return 30:00. If you get very strange amounts then you probably
have something else than 10:00 in your cell(s). 34:00 perhaps ? <g

I am trying to Sum times...

10:00
10:00
10:00


The programing I have used is =SUMIF(B1:B31,"0")

It seems to work, however when the Sum comes up it shows 6:00
Not 30:00.
I have been working with the formating of the time cells as well, but get
very strange amounts when I change hh:mm to [h]:mm.

Can someone please help.

Thanks
