use this formula for Cell J3
=(SUMPRODUCT(($C$2:$C$160=J2)*($D$2:$E$160)))/SUMIF($C$2:$C$160,J2,$D$2:$D$160)

Open in new window

Cell K3
=(SUMPRODUCT(($C$2:$C$160=K2)*($D$2:$E$160)))/SUMIF($C$2:$C$160,K2,$D$2:$D$160)

Open in new window

Cell L3
=(SUMPRODUCT(($C$2:$C$160=L2)*($D$2:$E$160)))/SUMIF($C$2:$C$160,L2,$D$2:$D$160)

Formula requires same name in column A and B in the row, but it has to be A or B.
To get the product sum $D$2:$E$160 must be $D$2:$D$160*$E$2:$E$160

With the names in column I, the formula in J3 will be.
=(SUMPRODUCT(($A$2:$A$160=$I3)*($C$2:$C$160=J$2)*$D$2:$D$160*$E$2:$E$160)+SUMPRODUCT(($B$2:$B$160=$I3)*($C$2:$C$160=J$2)*$D$2:$D$160*$E$2:$E$160))/(SUMPRODUCT(($A$2:$A$160=$I3)*($C$2:$C$160=J$2))+SUMPRODUCT(($B$2:$B$160=$I3)*($C$2:$C$160=J$2)))

Copy down and across for all names.
See sheet.
