Counting formula

[lawhawg]

I need a formula to sum on the cells that match a variable in another cell

A B C D E F G H I
1
2 Bo Jim Ron
3 3 2 6
4 1 2 3 4 5 6 ? ? ?

What I need to be able to do is sum the number of columns (A4:F4) that
matches the numbers in G3:I3. So, the sum I'm looking for in G4 is 6 (the
sum of A4:C4) or 6. H4 would sum to 3 and I4 would be 21. Can you help me
please?

Try this...

=SUM($A4:INDEX($A4:$F4,G3))

Copy across.

Note that if G3 is an empty cell the formula will sum the *entire* range.
