Does anyone know of a good way to find largest value in a column B, if and
only if it satisfies the criteria in column A? Much like a sumif or
countif.
For example, I have spreadsheet that lists all of my stores by market and
by
region, within those sheets. I am trying to find the largest value for
each
particular region. So I need the formula to look in column A for all
instances where the region is equal to region 1, and then find the largest
number in cloumn b that corresponds to all instances of region 1. I know
I
can do this by sorting my sheet by region, and locking down my ranges
manually, but I run this file monthly and I have stores that open and
close
without my knowledge. Any thoughts?
