Hello,
I would like to be able to sum numbers in column I based on conditions in
A,B,C . The formula below works
=SUMPRODUCT(($A$112:$A$1155=$A$14)*($C$112:$C$1155 =$C$14)*($B$112:$B$1155=$B$14)*(I$112:I$1155))
Now I would like to make the condition in each column optional, so i can use
the same formula if I want to sum column I only conditions in A and B for
instance (ignoring C)
Something like if($A$13=true,($A$112:$A$1155=$A$14), etc
How can I combine this in one elegant formula?
Any help is appreciated.thanks
