I need to only count the "C" in one array, but only if there is a C1 in the
adject cell

I am not understanding the (--, please forgive me if this is a stupid
question, it's late and I am tired and need to finish this for a report in
the morning.

Thanks

Hi!

Each element of the arrays:

(A1:A100="C")
(B1:B100="C1")

return either TRUE or FALSE

"--" converts these to 1's and 0's which Sumproduct can then process.

I will give it a try, I just posted this same question but a lot more
detailed, maybe it will make more sense. I am not familiar with this type of
formula, so I am not sure it will work. Please read my other posting.

You are the bomb! IT WORKS!!!! I have never known anything about t he '--'
before and I am not clear how it works, but it did - perfectly!
