[development] How can I refer to the shopping cart using document.getElementById if it does not have an id?

Do you have any JS errors in your firebug console?

What do you mean by "all the other ones after that did not complete?" Your
CSS files aren't loading?

If you are aggregating JS or CSS you will need to clear the Drupal cache.
Make sure to hold shift and click refresh in your browser such that you
aren't caching JS or CSS in your browser either.
