index/match formula problem

Hi,

I'm trying to do an index match formula to look up a name and number in a pivot table but the two values I'm looking up and concatenate are in the same row:

{=INDEX(A:B,MATCH(H5&I4,A:A&A:A,0),2)}

So in this formula, I'm trying to find a total sum in a two column pivot table that matches two criteria in H5 and I4 and searching for those two values in the same column of the pivot table (column A)
It's giving me an #N/A value.

The spreadsheet is attached below

Thanks!
