Small glitch with the Billing and Shipping Address forms: If you change the selected country, the State/Province combo is replaced by a textbox, but the value remains. So if you had, for instance "Florida", you'd get "FL".

Major problem: The process crashed after entering my billing information and hitting "Proceed to Next Step".

Edit: My street name has an apostrophe: that broke your code. Adding a second apostrophe solved the problem (e.g.: O''Reilly)
