Try this in C15

=INDEX(C2:C12,MATCH(A15&B15,A2:A12&B2:B12,0))

'This is an array formula which must be entered with CTRL+Shift+Enter and NOT
'just enter. If you do it correctly then Excel will put curly brackets around
'the formula{}. You can't type these yourself. If you Edit the ranges
'then you must re-enter as An array
