I have this code in my product page. it’s working fine but my product options no longer work.


<br />
<script type="text/javascript" src="http://books.google.com/books/previewlib.js"></script><br />
<script type="text/javascript"><br />
GBS_insertPreviewButtonPopup(['ISBN:{$product.product_code}','ISBN:{$product.product_features[2].value}']);<br />
</script>
```<br />
<br />
Any idea how I can resolve the conflict?<br />
