you have the site up to use paypal standard as the gateway. If you look at the form on the confirm page, the action of the form is to post to the paypal server, this means PayPal standard
On the confirm page, Do you see server behaviors for Storing the cart Summary and Cart Details in the database?
If not, you will need to add those to the confirm page, and also add universal email to send the order information in an email, then change the action of the form on the confirm page to point to itself.
I see in your order history that you have eCart 5, it may be easier to just delete the existing checkout pages, and re run the wizard, in the checkout wizard, you can select the No gateway option.
