Hi Sury, and Welcome to the Forum!
You may want to simplify your data/workbook for the purposes of this forum. When opening your workbook, there are many sheets and I'm not sure where you are wanting to do what you have asked about in your question. I assume you mean the dashboard, but since its not the first thing I see when I open the workbook, I'm not certain.
Also, if your data is confidential in any way, you might want to dummy it down when posting to the forum. While most folks are friendly and reliable here, it is always a good idea. If you're not sure how to do this, I think this thread will be helpful: http://community.tableau.com/message/213297#213297
As for your workbook, when you say "if the person is not 'White (Not Hispanic or Latino)'", do you mean the user (or whoever is logged into the dashboard on Server)? All of this is perfectly doable, but if you mean filtering based on who is logged in, that is one problem, while the action between dashboard/worksheet is another.
Here are the Knowledge Base articles on creating Actions and User Filtering:
I know that's a lot of reading material, but its all good stuff if you're going to be using Tableau often. Cheers!
