I am currently using Crystal Report XI.  I am trying to create a drop down list on one of the parameter fields.  The values in the drop down list come from a database view.  I added this database view as a new database field and linked it to the dynamic parameter field.   I had to enter my input parameter twice to see my expected result.   First time to see the drop down list and second time to actually run the main report procedure to extract data for the report detail lines.
