Use this calculation for your filter
IF [Workstreams] = "Total" THEN "True"
ELSEIF [Workstreams] = [Product] THEN "True"
Be sure that your Workstreams parameter uses the exact names as they appear in the Products field (case sensitive)
Once it's working, you can alias the parameter members using the right hand column "Display as"
