It looks right to me. 20:00 - 20:00 = 0. 0*25*24=0 If you want to assume that the second 20:00 is the next day, then use an IF statement, such as if C=0 then C=24. But what would you do when someone works 25 hours? How would you differentiate that from 1 hour? Therefore I would advise you to do one of two things: 1) Include the date as Joe suggested. 2) Convert the times to datetime, store that internally and make your calculations off of it, but display only the time. That might be a bit complicated for a spreadsheet app, though. -- Dotan Cohen http://what-is-what.com http://gibberish.co.il א-ב-ג-ד-ה-ו-ז-ח-ט-י-ך-כ-ל-ם-מ-ן-נ-ס-ע-ף-פ-ץ-צ-ק-ר-ש-ת ä-ö-ü-ß-Ä-Ö-Ü
