I'm new to excel...but I know SUMIF checks an array for a particular
value and adds up the cells in a corresponding array for matches. Say
I have three columns A=Salesperson, B=Item Sold, C=Amount. I want to
sum up the total amount that salesman i sold of item j. I know how to
find the total for all things a particular salesman sold, and i can
find the total for all sales of a particular item, but how do i find a
total of all sales by a salesman of a particular item? I know there
are ways to implement this with filters and tons of other ways, but
with the way the data is available to me, some kind of modified sumif
strategy would be best
