Array push not working??

[flashpipe1]

I've got the following code loading some xml, creating dynamic arrays and pushing the data into the array...

I pulled some pieces out because it seems like each push overwrites the previous entry and I'm not sure why it's not working?! I posted the xml and code (without the trace statements) below, and also attached the fla and xml files in a zip...if anyone has an idea what I've got wrong that would be GREAT!!!

var counties:XML = new XML();
counties.ignoreWhite = true;
counties.onLoad = function(success) {
	xN = counties.firstChild.firstChild;
	do {
		currID = xN.attributes.ID;
		var countyID:Array = new Array();
		_root["arr"+currID] = countyID;
		loadLocs();
		xN = xN.nextSibling;
	} while (xN.firstChild != null);
};
// Load the XML
counties.load("locsName.xml");
loadLocs = function () {
	nextN = xN.firstChild.firstChild;
	var tmp:Object = new Object();
	do {
		tmp.Name1 = nextN.childNodes[0].childNodes[0];		
		_root["arr"+currID].push(tmp);
		nextN = nextN.nextSibling;
	} while (nextN.firstChild != null);
};

and the xml:

<?xml version="1.0" encoding="iso-8859-1"?>
