One thing to check is that your login IDs in your data has been UPCASED. On our environment the SUB :: SAS.UserId returns a UPPER CASE value so I assume that's the case everywhere. If your data contains 'myuserid' then either change it to MYUSERID or use the UpCase function on your login category. To use UpCase in conditional grants you'll need to apply it through the batch tools since the editor doesn't have it listed under the Text(Simple) operators.    BTW -- I'm the Jason in the paper you reference.  🙂 ...

Three steps (haven't checked syntax): 1.  Create a Paramater called Selected Pageviews 2.  Create a new calculated measure called Pageviews with a IF THEN ELSE statement that checks the value of the paramater.  For example:        IF 'Selected Pageviews'p = 'Website A' THEN 'Website A'n                  ELSE WHEN 'Selected_Pageviews'p = 'Website B' THEN 'Website B'n                  ELSE RETURN 0        END 3.  This is the tricky part.  You need to create a calculated category that will contain 2 values (Website A and Website B) so that a dropdown or button bar selector can be populated for the paramater selection.  I try to find a category in the data that I know will not every be filtered out completly and assign the values to a group.  Maybe use a Custom Category instead of a calculated category will work best.  Once that's created then assign the paramater to the control (dropdown or button bar) and use the new Pageview measure on the line chart.  Don't use the Website A/B measures anymore on the visualizations.   When you change the button bar or dropdown the line chart should change.   Hope this helps!   ...
