Using VLOOKUP inside SUMPRODUCT = complex problem
Hi,
The shortest version I came up with uses the idea below:
If you rearrange you lookup table to look like this
a b
0,5 1
Then you can use:
SUMPRODUCT(B1:B3*((A1:A3=C1:D1)*C2:D2))
if you don't want to do that then you can use the longer formula
=SUMPRODUCT(B1:B3*((A1:A3={"a","b"})*{0.5,1}))
which turns out to be exactly as long as using SUMIF.
or the still longer version
=SUMPRODUCT(B1:B3*((A1:A3=TRANSPOSE(C1:C2))*TRANSP OSE(D1:D2)))

I have an excel model quite complex with the followinf layout
(drastically simplified):
col A col B col C col D
row 1: a 3 a 0.5
row 2 b 4 b 1
row 3: a 5
I need to calculate, by means of a sumproduct function, the
calculation:
(3*0.5 + 4*1 + 5*0.5) = 1.5 + 4 + 2.5 = 8
I have tried =SUMPRODUCT(B1:B3,VLOOKUP(A1:A3,C1:D2,2,0)) but it does
not work.
I have also tried the above formula using Ctrl-Shift-Enter, with the
same result.
Because my model is really complex, I do not want to use auxiliary
columns for intermediate results.
Is it possible to use SUMPRODUCT the way I need?
