Examples:
Get the display URL for a course section on a WebReg module.
Uses the Sections datasource to obtain the schID. Because the URL portion and schID are different data types, the schID needs to be converted to the matching data type.
'http://registration.xenegrade.com/YOUR-URL/coursedisplay.cfm?schID=' + CAST([YOUR-DATASOURCE].[dbo].[Sections].[schID] as varchar)
