I'm a little confused and need some help.

I'm loading in some information from an xml file and trying to store the info into different arrays.

var myArray:Array = new Array();

function processContentsOfXML(contents_xml) {
var sections= contents_xml.childNodes[0].childNodes[0].childNodes.length;
var loadedVar1 blar blar...
var loadedVar2 blar blar...
for (var i = 0; i<sections; i++) {
myArray[i] = new Array();
myArray[i].push(loadedVar1,loadedVar2);
}
}

All the information is loading in fine. The thing I'm confused at is why all the info is being pushed into just one array. I'm asking flash to set up a new array for each section that is in the xml. When I trace myArray0 or myArray1 I get undefined. When I trace myArray, all the info for the two sections are there.
