Index and Match Function across multiple array

Hey everyone

I'm experiencing a little difficulty in trying to apply the match function to multiple arrays. My goal here is basically to use it across multiple data sets (matrices)

This first formula works perfectly but only applies to one data set

=INDEX(A1:Z13,MATCH(T18,A1:A13,0),MATCH(T19,A2:Z2,0))

I try to apply this to two and I get a #value! error in

=INDEX(A1:AW13,MATCH(Y18,A1:A13&AB1:AB9,0),MATCH(Y19,A2:AW2,0))

I've tried multiple formulas and cant seem to get it to work. Any help will be appreciated. Thanks!
