All of these use the same #__xxxregion table
1. Country is value=id, title=name, WHERE country=1 AND published=1
2. Region is value=id, title=name, WHERE city=1 AND published=1, filter is where Country is parentid=id of Country
3. Location is value=id, title=name, WHERE country=0 AND city=0 AND published=1, filter is Region where Region is parentid=id of Region
I got this to work before in earlier versions of Easy Profile 1.x but it doesn't seem to work any more
