Need help with INDEX function

Hello,

I am trying to create a formula for calculating a value automatically based on intersecting points on a table. After some research it looks like the INDEX and MATCH functions are the most suited to help me.


Here is what I currently have in cell I5:

=INDEX(W16:AA21,MATCH([@[Total Net Order Conv Rate]],W15:AA15,1),MATCH([@NABV],V16:V21,1))



I am getting the #REF! error and I can't figure out why. Any help would be much appreciated!
