Ok, I gues I got it.
Open footer.php and find

echo "</body>\n</html>\n";

And place above the code and the result must be

echo '<script src="http://www.google-analytics.com/urchin.js" type="text/javascript">
</script>
<script type="text/javascript">
_uacct = "UA-4576980-1";
urchinTracker();
</script>';
echo "</body>\n</html>\n";

Thanks for all
