Checkout button not linking to payment page

Hello, currently in Preview mode. I am using mobilia. The problem is with the Checkout Button (See the end)

When I click on a product I have the buttons “Add to Cart” and “Buy It Now”. No Problem Adding to the Cart or with the Buy It Now Button

The Buy It Now takes me directly to the Customer Payment Page etc - No Problem

However after I click on the Cart Button, check-out button and it just refreshes the cart with the exact same screen. There is no redirect to the payment page.

Any assistance or suggestions would be greatly appreciated, so I can go-live. Thank you kV
