Hi @PhillipK ,
The drop-down list has a numeric value that only indicates that you created the parameter and assigned values to it.
However, if the report cannot be displayed when the parameter is selected, you need to consider whether filtering has been added to the dataset query.
You can add Filters to a dataset or use the following Where clause in a dataset query:
WHERE Production.ProductInventory.ProductID IN (@ProductID)

Also, confirm that you created any Tablix or text boxes or charts instead of blank reports.
Best Regards,
Joy
