buttons open the next page with "Facebox" modal popup plugin (which is the official 3rd party modal popup plugin that works based on jQuery and it comes with Virtuemart: /components/com_virtuemart/assets/js/facebox.js)

Those button run AJAX loading to load the shipping&payment methods, they are also prerequisite jQuery to run properly.
The reason why the jQuery based plugins don't work, is because you have 3 critical conflict problems in the shopping cart page, which breaks every thing that require jQuery.
Since our template (FashionMart) is not responsible for those conflict, we are not responsible to resolve them for you. You should resolve and eliminate the functions that create problem, from these files:
Visit your website with Chrome or Firefox browser, open the "Inspect Element" panel to see the console errors, so you would better see what line exactly generate the conflict problems.
TIP: I am seeing you are loading jQuery1.8 through jQueryEasy plugin, but it is pretty new library to run Virtuemart and old Joomla Templates. (your joomla template seems old to me, but i might be wrong). Most of the Virtuemart/Joomla related extensions are developed to work with jQuery1.7 or older.
Lower the jQuery version to jQuery1.7 or jQuery1.6 and see if things solved by itself
Eliminate the functions (from the JS files i have declared above) that doesn't work with jQuery1.8
This is all i can guide you on this. If you need any further support, you should purchase premium support and let us take care those problems for you:
