The formula

=IF(SUMPRODUCT(--($C$4:C4=C4))1,"",SUMPRODUCT(--(C4:$C$501=C4),H4:$H$501))

is too expensive. Invoke instead:

=SUMIF(C4:$C$501,C4,H4:$H$501)

If necessary:

=IF(COUNTIF($C$4:C4,C4)1,"",SUMIF(C4:$C$501,C4,H4 :$H$501))

The average formula can be modified to excluse 0's...

=AVERAGE(IF(Range0,Range)

confirmed with control+shift+enter.

Howdy All,

I have a spreadsheet that contains a couple instances of a formula similar
to this one:

=IF(SUMPRODUCT(--($C$4:C4=C4))1,"",SUMPRODUCT(--(C4:$C$501=C4),H4:$H$501))

The formula works great, with one exception.

It leaves a 0 value in the cell below the last instance.

This interferes with an AVERAGE formula that I am running on a column.

Any ideas on how to either eliminate the 0 value, or modify my AVERAGE
formula to not count the 0 value?

Thanks,
Brian
