Hi,

Within Excel 2007, I need to calculate the average of the following time values in days, hours, minutes and seconds :

00:18:09:26
00:05:34:50
00:07:41:06
01:22:52:55
00:00:55:48

I've tried using =AVERAGE(A1:A5) and changing the format of the values to various settings, but keep getting DIV/O as the result.

Help ????
