(EXCEL 2003)
Cells [A1:A4300] I have time values of phone calls in hours, min, sec.
Example:

0:11:34
1:04:45
....


if i use =SUM(A1:A4300) I get an output of: 146:09:49 I then want to take
the number of days that the person worked (110) during this data set to find
an average time per day on the phone.

I don't think I am getting the correct output:

Suggestions?
