Hi,
I a few sets of data that would have varying rows, and I need to get the
summation of products of cullumn B*C. How should I do this in excel? using
sumproduct(B:B,C:C) gives me a num error. I want to be able to have this
dynamically updated, hence, I don't want to do this in a macro(unless a macro
can be automatically executed).
Thanks
