Checkout Buttons Not Working

[new12]

Hello,
A client's website is having trouble with the buttons to save information and continue through the checkout process. The website is http://hshangout.com/store/, and I am using Joomla 2.5, Virtuemart 2.0.22b, and the RocketTheme Infuse template. When I disable the Virtuemart CSS in the Configuration, all the buttons show, but everything is jumbled. Most of the buttons show if I switch to the Beez 5 template, as well. How do I fix this?

Thanks!
Evan
