Expression - want 0 results only

[Scottie31]

I'm trying to run a query that has a 3 expressions within the query. I'm using the following:

Exp2-Exp1 this would be the results for Exp3.

The problem I am having is that I only need the results for Exp3 to be returned if they equal "0".

Any help would be appreciated.....Thanks
