On page 19, the script is completely wrong and drove me mad: variation-content should be variation_content and document.write(“</nosc” + “ript>”) should be document.write(“<nosc” + “ript>”);

So, here is he complete correct script:
<script>
var v = utmx(‘variation_content’, ‘Section1’);
if (v) {
document.write(
v.replace(“%%product_name%%”, “<? print $product_name ?>”).
replace(“%%product_price%%”, “<? print $product_price ?>”).
replace(“%%product_id%%”, “<? print $product_id ?>”));
document.write(“<nosc” + “ript>”);
}
</script>
<ul>
<li>Product name: <? print $product_name ?>
<li>Product price: <? print $product_price ?>
<li><a href=’buy.php?prod-id=<? print $product_id ?>’>
Buy Now</a>
</ul>
</noscript>

Adapt it to your code and be happy!

Give it a try!
