Great thanks! I really like the firt formula, but now the average is
including cells that do not have a vaule. How can I use this same formula,
but have the average only include cells that have numbers in them? Thanks
again for all the help!

=AVERAGE(IF(NOT(ISERROR(C1:C3)),C1:C3))

which is an array formula, it should be committed with Ctrl-Shift-Enter, not
just Enter.
Excel will automatically enclose the formula in braces (curly brackets), do
not try to do this manually.
When editing the formula, it must again be array-entered.

Note that you cannot use a whole column in array formulae (prior to excel
2007), but must use an explicit range.

I am making a spreadsheet in excel that will add subtract times and then
average the totals of multiples of these. My problem is that some of the
tiems do not need to be entered causing a # VALUE! in teh line where my
subtraction formula. This is fine and needs to stay this way. My problem
is
that the average then has a #VALUE! instead of an average. How do I skip
over cells that have the #VALUE! ? I ammaking htis spreadsheet for
someone
else, so I can not correct it each time this happens. This is what my
sheet
is like:
A B C
1 1:15 1:30 15 =(B1-A1)*1440
2 12:30 1:00 30 =(B2-A2)*1440
3 3:15 N/A #VALUE! =(B3-A3)*1440
4 #VALUE! =AVERAGE(C1:C3)

Any suggestions to get the average to actaully average the amounts that
are
not #VALUE! ??? Any help would be fantastic!!
