"Conditional" sum

[davor]

Please help. I have "input" data like this:

AA BB AA DD CC
--------------------------------------------------------------
8 10 8 8 8
10 10 10 10 8
12 8 7 12 8


Is it possible to have "output" data, summarizing all numbers for AA,
BB, CC... etc., something like this:
AA 55
BB 28
CC 24
DD 30

I have lot's of AA BB CCs and lots of values for them. If there is
some usefull formula please help me!
Thank you in advance!

try:
=SUMPRODUCT((A1:C1="AA")*A2:C4)

Assume source "input" data as posted is within A1:E4,
with top row headers: AA, BB, AA, etc

Assume the headers are listed in G1 down: AA,BB,CC, etc

Put in H1:
=SUMPRODUCT(--ISNUMBER(MATCH($A$1:$E$1,G1,0))*$A$2:$E$4)
Copy down
