Try this:

=SUMPRODUCT(('List of Reviews'!B1:B1000="Web")*('List of Reviews'!
D1:D1000=1))

Adjust the ranges to suit your data, but you can't use full-column
references (unless you are using XL2007, in which case you could
probably use COUNTIFS).

Hope this helps.

I am using the following formula to count the number of times "Web" appears

=IF('List of Reviews'!B:B="Web",COUNTIF('List of Reviews'!D:D,1),0)

I continue to get a #NUM! error for the logical test in the IF statement
even when the formula is reversed and I try to count the number of times
"Web" appears for every row which contains a "1" in column D. What is wrong
with the formula? Is there another function that will return the correct
result? Just a note: The COUNTIF function works each time to find the right
value for the criteria entered. Help needed quickly! Thanks.
