dbColGraph problem

I'm trying to use the dbColGraph function to implement a rating system (1 to 5 stars). When I use MyDb.dbColGraph="themes,Rating,65,,star.gif,3, 1,85" it works O.K. when I delete the last 2 properites and use MyDb.dbColGraph="themes,Rating,65,,star.gif,3; " I get the error message:

Microsoft OLE DB Provider for ODBC Drivers error '80040e10'

[Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1.

/themes/sample3.asp, line 92

I'm not using the dbRecordSet property so why are these final 2 properties needed?
