can't set global array

[copeZero]

This is the darnest think, so why is it that one cannot set a global array in a function, ive tried many ways but nothing works... grrr, i just can't figure this out...

var xmlDoc:XML = new XML(); 
System.useCodepage = true; 
xmlDoc.ignoreWhite = true; 

xmlDoc.onLoad = function(ok:Boolean) { 
if (ok) { 

var num:Number = this.firstChild.childNodes.length; 
var num2:Number = 0;
var test1 = this.firstChild.childNodes[0].childNodes[0].attributes.modname;

// sometimes the first value does not exist, so skip it
if (test1.length==0) {num2=1;}
var f:Number=0;

for (var i = num2; i < num; i++) { 

_global.aLabels[i]= this.firstChild.childNodes[i].childNodes[0].attributes.modname;

// if i check for _global.aLabels[0] or [1] many frames 
//later i get undefined.
// At this spot in this function if i:
// trace(_global.aLabels[0]);  I get a value
// so why can i use the array later?  Thanks


}
	   
   } else { 
       trace("XML did not load"); 
   } 
};

xmlDoc.load("test.xml");

figired it out...
in the code above instead of using an array i'm calling a function to do the work:

var f:Number=0;

Code:
for (var i = num2; i < num; i++)
{
f = f +20;
chekbx(this.firstChild.childNodes.childNodes[0].attributes.modname, f);
}



Code:
function chekbx(val,num){
var depth:Number = this.getNextHighestDepth();

var val2:Number = num;

var cchItem:mx.controls.CheckBox;

var param bject = {_x:100,_y: val2+100,label:val};
cchItem = this.createClassObject(CheckBox, "cch"+val2, depth++, param );
cchItem.addEventListener("click", oListener);
trace(20 * val2 + 100);

cchItem.move(400, val2 + 100);

};
