BAQ filter help

I have a fairly simple BAQ and drawing a blank how to filter this. Maybe I need to do on the dashboard not the BAQ?

I have a calculated filed and I only want the results to be if that calculated field is greater than Zero (Circled in red)

UPDATE I added the filter on the Dashboard and seems to be working fine.

You could also change your Top-Level query (with that calculated field) to a Subquery, then create a new Top-Level query and call only the new subquery/old top-level query. Then you can add a filter criteria on the calculated field.

You could add a SubQuery Criteria. This is applied after the results of the subquery are determined.
