How can I build a date in a query that is used for filtering purposes? The data is in the records in two fields - Month and Year. In our query we have an expression that builds a date - DateRange: [Month]/1/[Year] in order to qualify the record with the criteria Between FromDate and ThruDate. DateRange as it is shown here returns a date of 12/30/1899 for all records. DateRange: #[Month]/1/[Year]# is invalid syntax. DateRange: [Month] & "/" & 1 & "/" & [Year] is not recognized as a date.
