Im having problems with my Display formula in my REPORT.
This is my Code and ERROR always appear:

A number, currency, datetime, etc or string is required here.

{ovr_1.LoanTypID} in ["02", "04"] and
{ovr_1.StartPayDate} <= {?Pm-@ReportDate} and
({ovr_1.EndPayDate} >= {?Pm-@ReportDate} or {ovr_1.EndPayDate} <= {?Pm-@ReportDate}) and
{ovr_1.LocID} = 27 and
{ovr_1.AccTypID} = "1" and *and cursor is pointed in this area*
({View_LastTransFIN.LastTrans} > (cdate({ovr_1.Year},{ovr_1.Month},cdbl({ovr_1.DueDateFin})))) <= {?Pm-@ReportDate}

I dont know what's wrong here.

i am reading the last line as a boolean evaluation

it presents an error if i remove the " though. Thanks for the tip.
