I have a saved search with 4 of these formulas

CASE WHEN trunc({today})-({created}) < 30 THEN {amount_due} ELSE 0 END

on my results tab and two simple criterias

Status: Closed Won

and

Rep = Mine.

I have a total of about 11000 results if I remove the criteria

Rep = Mine

and the search loads fine, but if I add that criteria back, the search keeps on loading but does not display anyhing. Does anyone know how that can be fixed?
