Pages will show all values only. We can use the filters and achieve it. Don't use pages for this requirement.
As sankar mentions, with Pages, you will always see all possible values displayed -- I understand your frustration with this. With the addition of Story Points in version 8.2, I would think you could use that feature to accomplish this. I think you may be using an older version of Tableau, like Version 8.0 -- upgrade to 8.2, and you can utilize Story Points, which will allow you to filter for a particular value on one "page" (Story Point), then set the next "page" to a different filter value, etc.

Thanks Matthew. I'm using Tableau 7.0. My goal is to have the filtering occur automatically because I have 70 different combinations. But it's good to know it might not be available in Tableau 7.0.
