No, I meant Activesheet. What I didn't mean was to keep the .Value

Activesheet.Evaluate("SumProduct((rng1=chk1)*(rng2 =chk2),rng3)")

Thanks, Bob. I think that will work. Assuming of course you meant
"Application"

This is great as I have previously been using array formulas, but I
think
this may make things less susceptible to error.

But I have a related question:
How might you use this formula inside a VBA function? I know through
code
that I could step through all the data, but that takes a long time,
Excel
seems to do this formula very quickly. And when you might have alot,
time
is
critical.

The formula
= Application.WorksheetFunction.SumProduct((rng1.Val ue = chk1) *
(rng2.Value
= chk2), rng3)

does not seem to work, any suggestions.

Sumproduct only works on arrays of numbers.

In your case, You need to convert the first argument to numbers. By
creating two arrays of booleans and multiplying them you do that.
Bob
showed you a way to do it by using two negation operators without a
dummy
column.

this also works
=SUMPRODUCT(1*(C2:C71),(C2:C7))

but purportedly the double negation is faster.

You could test if the value is a number like this:
=SUMPRODUCT((ISNUMBER(C2:C7))*(C2:C71),(C2:C7))

The following formula works:

=SUMPRODUCT((C2:C71)*(C2:C7<100),(C2:C7))

HOWEVER, if I remove the logical expression (C2:C7<100), then
my
formula
does NOT work because in cell C5 is a text value..

How can I use the sumproduct formula without inputting the
unnecessary
array...C2:C7<100??

Thamk you,
