I see you've got our Cart Script code in that page, so it should work, but perhaps our script is conflicting with some other javascript in your page, probably something that catches clicks on "external" links to other sites..
One thing to try is changing the box.js
in our Cart Script code to box_fb_n.js
like so:
<script type="text/javascript" language="javascript"> function EJEJC_lc(th) { return false; }; </script>
<script src="https://www.e-junkie.com/ecom/box_fb_n.js" type="text/javascript" language="javascript"></script>
Then reload your test page to see if that solved it. If not, try moving our Cart Script code around to different locations in your page, before/after other javascripts you're loading there -- e.g., try near the start or end of your page HEAD section, or near the start or end of your BODY section. Sometimes it matters which scripts load before/after others in the same page.
