Need Help!

This is a super simple XML data pull… not sure why it isn’t working. Any ideas what I’ve done wrong?

The dynamic text field has been labeled as "prizepool_formatted_txt’

The actionscript is

function loadXML(loaded) {
if (loaded) {
	_root.prizepool_formatted = this.firstChild.childNodes[0].childNodes[3].firstChild.nodeValue;
	prizepool_formatted.text = _root.prizepool_formatted;
} else {
trace("file not loaded!");;
}
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("http://www.mydomain.com/prizepool.xml");

and the XML file is formatted like so:

<data>
   <updated>March 17, 2006, 8:04 am</updated>
   <timestamp>1142604293</timestamp>
   <prizepool>1034</prizepool>
   <prizepool_formatted>$1,034</prizepool_formatted>
</data>

Keep getting “undefined” error! Any help would be greatly appreciated.
