Hello
I have a grid of data, down the left is 2 columns for product item and
description, along the top are months. I need a formula function to search
along the top to find the correct month, then search down the 1st column to
find a product match, then search down the 2nd column to find a description
match. The intersection of the correct row(s) and column being the value i
require. There may be several returns matching the same criteria, so the
results need adding together.
Previously (xl2003) we used a sum(if array but it is slowing the
calculations right down. Now (xl2007) I have looked into the new sumifs and
getpivotdata but can't get any sense out of either. I can do a custom
function, but at the moment would rather keep it standard.
Any ideas
Thanks
