Error #1006: value is not a function on Contact Form

programming flash
1

Hi,

I have followed a tutorial for a email validation contact form perfectly (to my knowledge) but I keep getting an error when the form is filled in correctly or correctly apart from the email input:

TypeError: Error #1006: value is not a function.
at roberts_fla::contactForm_46/SubmitFunction()

This obviously points to the SubmitFunction() in the AS3 but I don’t know why:(

/*To Define The Main Varibles*/
var urlLoader:URLLoader = new URLLoader();
var imgLoader:Loader = new Loader();
var loadFunction:URLLoader=new URLLoader  ;

/*XML Request*/
function XMLFunction(XMLPath:String):void {
    urlLoader.load(new URLRequest(XMLPath));
	urlLoader.addEventListener(Event.COMPLETE, onSuccess);
}
//The Name of the XML File
XMLFunction("ContactXML.xml");

/*XML - Flash Actions*/
//We'll define "info, title and image" varibles to use them in XML File.
function onSuccess(e:Event):void {
	var xml:XML=new XML(e.target.data);
	contactInfo.htmlText=xml.info;//We use HTML to show any type of texts
	contactInfo.autoSize=TextFieldAutoSize.LEFT;//AutoSize-Left
	/*contactTitle.htmlText=xml.title;
	contactTitle.autoSize=TextFieldAutoSize.LEFT;*/
    imgLoader.load(new URLRequest(xml.@image));
	imageMc.addChild(imgLoader);
}
