index match not returning any results

Hi Gurus

In the attached I have an index/match formula in B15 that I cant get to return any results not even a N/A#

Any advise would be welcome.

Thanks

I think you could do this with the matrix layout instead of the array layout:
so it's like:
INDEX(matrix, MATCH(down), MATCH(across) )

For you specifically:
B15 =INDEX(Edges!$B$2:$E$200,MATCH(Sheet2!B14,Edges!$A$2:$A$200,0),MATCH(Sheet2!B12,Edges!$B$1:$E$1,0))

That doesn't have any special error handling.
