I think we've already responded to you via email, but in case anyone with a similar problem happens across this thread, the problem with cart buttons not seeming to do anything at all when clicked is usually due to some glitch in the View Cart code on the page. If you compare your standard View Cart code from E-junkie Seller Admin with the View Cart code in your site, you should be able to spot the difference.
In your particular case, it appears that this line in your page has the significant glitch:
<script src="box.js" type="text/javascript"></script>
...which should really look like this instead (as provided in Seller Admin):
<script src="http://www.e-junkie.com/ecom/box.js" type="text/javascript"></script>
Your page design/editor software may be making that change automatically when you save the page; look for an option/preference setting that says something about changing remote scripts to local, or similar such wording. That setting may be telling your editor to take the reference to the "http://www.e-junkie.com/ecom/box.js" cart script on our server (as given in our original code) and convert that into a reference to a copy of "box.js" on your own server (as saved to your page), and that latter setup just won't work.
If you can't get this sorted out, just remove all the following lines from your page's View Cart code, and then all the buttons should work in "fallback mode" by opening the cart in a separate window/tab:
<script language="javascript" type="text/javascript">
<!--
function EJEJC_lc(th) { return false; }
// -->
</script>
<script src="box.js" type="text/javascript"></script>
