Whenever javascript is disabled in the buyer's browser, or in any other scenario where the standard overlay-style cart (which depends on javascript) cannot be displayed inside your page for any reason, the cart buttons in your page should continue to work just fine in "fallback mode" by opening a separate window/tab to display the cart.
You are the only one reporting this sort of issue, so that indicates something peculiar to your site. To troubleshoot any further, we would need more details about exactly what error message appears, and what steps were taken leading up to that error, with a link to the specific page where those steps are leading to that error.
One problem I noticed on your page is that the javascript portion of your View Cart code is misplaced at the very end of your page's source code, after your </body> and </html> tags, so that could be causing an issue. These lines can go anywhere between the <head> and </head> tags, or anywhere between the <body> and </body> tags, but the best place for optimum page-load performance would be before the </body> tag, as close as you can get to that tag:
<script language="javascript" type="text/javascript">
<!--
function EJEJC_lc(th) { return false; }
// -->
</script>
<script src="http://www.e-junkie.com/ecom/box.js" type="text/javascript"></script>
