I got asked to help analyze the employee survey results.

The spreadsheet is set up with like :
These are the question categories:
Dept Yrs w/Comp Q D Q R
A A 1 3 4 5
B A 1 3 5 6
etc.


I can't come up a formula to calculate the averages by category (i.e.
Q,D,R)

I tried simple arrays like =SUM((D2:AVQ2="G")*D3:AV25), but that errors out.

I tried HLOOKUP, but that only returns the value from one row.

Any suggestions?
