Hello,
I need a little help, I really can't come up with a solution to that little problem:
I have 4 excel sheets (same file) containing a bunch of lines. The columns in these sheets are:
SUP-CODE / DPT / SUP NAME / CONCEPT/ INVOICE / SUM...
I have a 5th sheet that I wish would contain a summary of the other 4 sheets.
Basically, I need a formula that return a sum by concept (from the data from sheet 1-4)
CONCEPT1 = $$$$
CONCEPT2 = $$$$
etc.
I could simply put all of them in the same sheet and use a filter tool to get that result, but I really need a more permanent function (that would also allow me to add lines in the different sheets and take them into account).
I hope it's clear. Any help (even a quick tip to follow) will be greatly appreciated
Benoit
