I have a cart full of nearly $100.00 of merchandise and the checkout isn't working. I had to get out of checkout and create my account first - at least that works. Pardon my limited understanding of coding but I don't see anything in there that actually allows any of those "Continue" buttons to actually do anything. Page one of "I want to use an existing address" - and there it sits.
Yeah - I did all the obvious. Cleared cache and reload pages a half dozen times - not working. Don't know what browser you coded this for but FF sure isn't happy with it.
