I thought as much. But then, I would have written COUNT(G8:P8,U8:V8) or
SUM(U8,V8) to be consistently extensible.

Just commenting on syntax, without vetting the solution....

What useful purpose does SUM serve in the context SUM(U8+V8)?

Also, reordering of terms will avoid some needless parentheses without
sacrificing readability, IMHO. To wit:

=IF(COUNT(G8:P8,U8,V8)12, "",
VLOOKUP(40%*SUM(G8:P8)/SUM($G$7:$P$7) +
60%*(U8+V8)/SUM($U$7:$V$7),GradeTbl,2))

Note: Perhaps Bob meant to write SUM(U8,V8). Although that can serve a
useful purpose sometimes, I think it is redundant here, given the
conditional test COUNT(G8:P8,U8,V8)12.

I'll take a punt anyway

=IF(COUNT(G8:P8,U8,V8)12,"",VLOOKUP((SUM(G8:P8)/SUM($G$7:$P$7))*40%+(SUM(U8+V8)/SUM($U$7:$V$7))*60%,GradeTbl,2))

but can you show some data t try it on

I have the following formula that works correctly. The formulas is
used to
calculate grades for my classroom.

=IF(COUNT(G8:P8,U8,V8)12,"",VLOOKUP(SUM(G8:P8,U8: V8/(SUMIF(G8:P8,"0",$G$7:$P$7)+SUMIF(U8:V8,"0",$U$7 :$V$7)),GradeTbl,2))

What I am trying to do is weigh the grades so the range G8:P8
constitute
40%
of the grade and the range U8:V8 constitue 60% of the grade, then
using
Vlookup show the grade.

I have tried Sum((G8:P8)*.4),(U8:V8)*.6)) in the SUM(G8:P8,U8:V8
part of
the
formula but get an error message. I have tried others with no
success.

Is it possible to accomplish what I am trying to do with one
formula?

Thank you.

and the formula in W9, copied and pasted:
=IF(COUNT(G8:P8,U8,V8)12,"",VLOOKUP(SUM(G8:P8,U8, V8)/(SUMIF(G8:P8,"0",$G$7:$P$7)+SUMIF(U8:V8,"0",$U$7 :$V$7)),GradeTbl,2))

Hope this helps....thanks again
