I have added the following snippet to define_ main_page.php


<script>
<script type="text/javascript">
var pageTracker = _gat._getTracker("UA-3580723-2");
pageTracker._initData();
pageTracker._trackPageview();
</script>

between <HTML> and <BODY>.

The purpose of this snippet is to create a Google Sitemap as instructed by Google.

I also placed this snippet in the same place on several of the products that I sell.

Although the main page appears fine I am getting the following error on the main page through the Web Developer.

unexpected end of XML source
pageTracker._trackPageview();\n


When I click on the product called “software” I receive the following error.
_
gat is not defined
<script type="text/javascript">

QUESTIONS:
1. Are these errors serious?
2. Is there a way to correct them
