issue with cart widget

Having a strange issue and could use another pair of eyes….

On this site: http://www.kickstartmedia.info/client15/

When you add something to the cart and then click “view cart”
it works fine. However when you click the red “checkout” button it just reloads the current page. The checkout button works fine from the cart just not the widget. Any ideas for me?
