Try this:

=SUMPRODUCT($C22:$AF22,$C20:$AF20)/SUM($C20:AF20)

To answer your question about 30 arguments:

Each set of inner ( ) is *1* argument

So:

=SUM((A1,A2,A3,A3,A5)) has 1 argument

=SUM((A1:A10),(B10:B20),(C20:C30)) has 3 arguments

I've tried to break this formula up into defined names but it is not
working
properly. Does anyone have any suggestions how I can get around the 30
argument limitation of the SUM function? Each argument is multiplying
a
number times a percentage.

Thanks!
