My submit button disappeared. I am running, Zen Cart 1.3.9h and Googlecheckout 1.4.7.

So i find a item, i click on add to cart the next screen is missing the googlecheckout button. When i view source the last thing i see is
<!-- * BEGIN GOOGLE CHECKOUT * -->
and then nothing else.

Anyhelp is appreciated. The site im referencing is celluradio.com/shop
