Hi, sweens319

Harlan mentioned that =COUNT(MATCH(Sheet2!C1:C100,ID,0))
is an ARRAY FORMULA.

That means you commit the formula by holding down Ctrl and Shift when you
press Enter, instead of just pressing Enter.
(It's often abbreviated as C+S+E)

When you do that, Excel will but braces around the formula {your_formula}
and it will return the correct value.

Note: You can just type the braces yourself.....you need to let Excel put
them in for you.

Not sure why, but the "faster" one didn't work. I still got a value of
zero.
Thankfully, the original function (sumproduct) worked exactly like I
hoped.
Thank you both for your willingness to help.

Try this:

=SUMPRODUCT(--(ISNUMBER(MATCH(Sheet2!C1:C100,ID,0))))
....

If recalc speed isn't essential,

=SUMPRODUCT(COUNTIF(ID,Sheet2!C1:C100))

should return the same result. If recalc speed is essential, I believe
the
array formula

=COUNT(MATCH(Sheet2!C1:C100,ID,0))

would be faster.
