Assuming the declaration is true, great job! There's a "but", though: I get a (rather ugly) 404 error if I click on my state without selecting a country first.

Assuming the declaration is true, great job! There's a "but", though: I get a (rather ugly) 404 error if I click on my state without selecting a country first. It wasn't obvious to me that I had to select United States in the first dropdown since the second dropdown already had the fifty states loaded it. You should disable the second dropdown until a country is selected, or better yet don't even show it until the user selects from the first one.
