Right click on the field where the time summation foruma is, cell properties, category time, somewhere in the list, there is a non module 24 time display. Btw, this is Office 2000. And it's dutch, so I tried to translate the menu's but I'm not sure they're correct. Claudio -----Oorspronkelijk bericht----- Thanks Peter for the reply. That is what I meant by modulo 24. But I need actual hours, even if it exceeds 24. e.g. say total hours are 27:30 then the total shows only 3:30. I cheked out insert|function but am unable to find any suitable function. May be I need to install some additional stuff? Though I don't know what. Vyas -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
