index match returns 0 for blank cell, want it to be "-"

Question

I have looked all over and tried a bunch of different things and non are working.

I can get the error to show - but I also want a blank cell to return -.

Right now blank cells are returning 0.

The blank cells appear in the $C$6:$DD$50 section if that helps.

=IFERROR(INDEX('Foundation Plates'!$C$6:$DD$50,MATCH($C9,'Foundation Plates'!$B$6:$B$50,0),MATCH(D$8,'Foundation Plates'!$C$5:$DD$5,0)),"-")

Answer 1

=Index(...) & “”

it would convert 0 (Blank value) to an empty string.
