title: tableau use either Country or State (only if country = usa) field as filter
body: <p>I am trying to display travel expenses by location in a Tableau map.  If the country = USA, then I want to filter by State, else filter by Country.  I can do either or but not both on the same map.  Where would I put this criteria?</p>
  
  <p>I am new to both Tableau and to this website.  I have tried to upload an image but was told my reputation needed to be a 9.  Is there any other way to share information?  Possibly dropbox?  </p>
  
  <p>Here is a link to my workbook:
