reload upon selection code

[protokop]

On my create account page the users select their country from a drop box and fill in their state in a text box. then they hit submit and it errors saying select state from drop box (now a drop box appears in place of the previous text box).

 

I moved the country to the top of the page, and i want the page to reload when the country is selected (or i want the state drop box to appear at least).

 

now my question is...

 

a ) is it simply only a few lines of code to get the drop box to reload, and could someone help me out with it (or get me started)

 

b ) is there a way of turning off the zones for state so that the state drop box isn't forced to load?

 

I'd prefer my first option, but if it involved long/specific code then i guess option b would be better.

 

hope someone can help me. thanks
