sorry AliGW: I did not mean to overlap

Thanks - title fine now.

What result do you expect to see in the yellow box? Please manually calculate and tell us.

Hi again,

you could try in Summary!B13 and to be copied to the right

=SUMPRODUCT(B$5:B$11,VLOOKUP(T(IF({1},$A5:$A11)),Data!$A$4:$M$20,MATCH(B4,Data!$A$3:$M$3,0),0))/SUMPRODUCT(VLOOKUP(T(IF({1},$A5:$A11)),Data!$A$4:$M$20,MATCH(B4,Data!$A$3:$M$3,0),0))

or (other approach):

=SUMPRODUCT(B$5:B$11,SUMIF(Data!$A:$A,$A5:$A11,Data!B:B)/SUMPRODUCT(SUMIF(Data!$A:$A,$A5:$A11,Data!B:B)))

There are for sure better solutions.
