Small bug/problem in template

We have Joomla installation with the Virtuemart Extension. We then bought a template from Yagendoo VaMazing, wich has either a conflict between templates or a bug in the code. The problem is that the Next-button in the checkout does not work (will not click). It was not a problem in the default theme, but is now in the Yagendoo-theme. Im sure its easy to fix, but coders are not available until next week and we need it fixed NOW. This is a small job, but we are looking for professional designers that we can work with in the future as well. When bidding on the project, please write JOOMLA VIRTUEMART
