Hi,

I trying to to use sumproduct only on visible cells and having a hard
time. I read through many help sites, but can't seem to get it to
work. Here's what I'm trying to do to a much larger file...

A B
1 2 300
2 2 200 (hidden/filtered)
3 3 100

How do I set up a formula to get 2*300 + 3*100 = 900?

Thanks.
