Sum of multiple index matches with tables

Question

I am trying to get the sum of associated columns from multiple different tables.

This works for one table, =INDEX(Table2[@W],MATCH([@[Franchise ID]],Table2[@[Franchise ID]],FALSE),1)

However when I try to add a second table, it throws an error =SUM(INDEX(Table2[@W],MATCH([@[Franchise ID]],Table2[@[Franchise ID]],FALSE),1),INDEX(Table224[@W],MATCH([@[Franchise ID]],Table224[@[Franchise ID]],FALSE),1))

How can I make this work?

The Exact Formula Is:

=SUM(SUMIF(Table2[Franchise ID],[@[Franchise ID]],Table2[@W]),SUMIF(Table22[Franchise ID],[@[Franchise ID]],Table22[@W]),SUMIF(Table224[Franchise ID],[@[Franchise ID]],Table224[@W]))
