[Zope] ZSQL select on date/time

Does anyone have a working example of how to select on a date/time column in an MSAccess database. Something like Arguments: FromDate:date select * from "Applicant Database" where [Date Received] > <dtml-sqlvar FromDate type=float> ...except the above syntax produces: Error type: sql.error Error value: ('07001', -3010, '[Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1.') ...regardless of value of type. -- Thanks -- Loren
