For example I go to the link I posted above, I add a dvd to the shopping cart, I click "proceed to checkout", I login, on the checkout page I see "billing address" under that a "new" button, on the other side is "Shipping address" and "Use the same address as for billing." Under that is the details about my order. Then at the bottom of all this is a button that says "next".
If I hit the "next" button this page just reloads. I keep hitting it, the page keeps reloading and I have no idea why I'm not taken to the next step. Shouldn't there be an error message at this stage saying that my checkout can't finish because I haven't entered in a billing address?
I added an image of what I see after hitting the next button, am I missing something?
