I have a vlookup formula
=IF(ISERROR(VLOOKUP(O2,data,10,FALSE))=TRUE,0,VLOO KUP(O2,data,10,FALSE))
which works fine, now I need to add another vlookup to this formula so that
the results sum both lookups. I've tried many ways, no luck yet, any ideas,
please send exact formula

Louie appreciates your help!
