CRE Loaded Checkout repair

Our checkout page has been having a lot of issues. Most recently, the shipping address information is gone. This must have been removed by a previous programmer, but we need the customer to be able to ship to a separate address other than the billing address. I will need you to test, thoroughly, the checkout process from adding an item to the cart to getting a confirmation # across IE, FF, Chrome, and Safari. When bidding, please mention "creloaded checkout issue" so I know you read this. Thank you.
