Formula Help

[excel_novice10]

Hello,

I am first time poster looking for help with a formula which uses a sumproduct and vlookups:

=SUMPRODUCT((VLOOKUP(__,__:__,{2,3,4,...},FALSE)>0)*VLOOKUP(__,__:__,{2,3,4,...},FALSE))


Here is a simple example of the formula in action:

While the formula works with small datasets, Excel's formula character limit prevents it from being applied to larger data sets, as there are too many index column numbers. How should I work around the character limit if I have too many columns (over 1000)? What alternative formula would work more efficiently and accomplish the same objective? I don't have experience using Excel VBA, so any solutions in vanilla Excel would be helpful.


Thanks for your help!
