Error #1010

I’m trying to load a simple line of text from XML in to dynamic text filed that is inside of a MovieClip on a stage. I think I did everything that has to be done, so why am I getting this error?.

TypeError: Error #1010: A term is undefined and has no properties.

var myXML:XML;var
myLoader:URLLoader = new URLLoader();
myLoader.load(new URLRequest(“test.xml”));
myLoader.addEventListener(Event.COMPLETE, processXML);
function processXML(e:Event):void {
myXML = new XML(;
this.cont_MC.test_field.text =[0]
