snb thx for your reply!
I don't really understand what you mean with: "check what the arguments of 'offset' mean", if you mean the explanation of excell what OFFSET does; returns a reference to a range that is a given number of rows and columns from a given reference. I checked it but then I still don't really get what I have to do/change in my formula (sorry I am not so known with excel and its terms)
The small change (switching 1 and 6) you did in the formula did not change the out come of my on formula (still #DIV/0!)
So I guess I do something wrong with OFFSET? Can you explain me about the arguments of OFFSET?
Thx
