Oh, OK. I have indeed been trying to wrap my brain around just how flexible and expandable Sumproduct is just for the sake of knowing. After reading your explanation, I can see why I got confused by what I read on some of the other web sites I've perused on the subject. I was lacking the proper context in which to interpret the specific examples they were addressing. Even those sites make more sense now.

Thanks!
