Hi @Terry St Jean
Are you trying to achieve this result? Add an "All" option in the parameter drop-down list, when "All" or "All" and other options are selected, all data will be returned.
Then you can try this approach:
- Add or ('All' in (@Parameter)) after the Where clause in the main dataset query;
- Add the "All" option to the query dataset. After the parameters are set normally, the result will be as I have shown.
If I misunderstood you please tell me more information.
