I actually did it both ways originally. I thought that the '--' were
strange so I left them out. The results were 0. I then did it with the
'--' and the results were #value!. Here is what I have input in fact I
just copied it from your post:

=SUMPRODUCT(--(E1:E29001=V1),--(F1:F29001=W1),--(H1:H29001))

I also tried the same formula but instead of cell references I used
text to replace V1 and W1. Same result. I then tried using E:E and F:F
and H:H instead of using the row numbers. Again, same results. Could
the version of Excel make a difference, I have 2003?

Thanks again for your assistance.
