You have to change the text in the link to this link:
<P><A class="LinkToThis" href="javascript
:void(0)" onClick="window.open('http://www.yoursite.com/store/linktothis.php?linkto='+escape(window.location.hre f),'','width=800,height=400,resizeable=true')">Lin k to this</a><!-- { $product.tmbn_url } --></P>
Make sure your site is in the text and that you do need to have the "store" directory
