Passing variables to a report

[kken]

I know how to pass 1 value to a report but I seem to be having prob passing 2 values. Here is the format to pass 1 value:
Report.rpt?sf={TableName.FieldName}=ValueToBePassedIn&user0=UserID&password0=password
Does anyone know the syntax to pass 2 values (both field names)

Thanks
