Need help with a flex builder Application, Where should I go?

Maybe you know whats wrong, or you can just show me how to make this flex application use an image file as a link to change content in an Iframe.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" backgroundColor="#FFFFFF" alpha="1.0" themeColor="#ffffff" width="902" backgroundImage="Background2dark.jpg" borderThickness="0" borderStyle="none">
<mx:Script>
 	<![CDATA[
 	
 	import flash.events.MouseEvent;

    public function createListener():void {
        buildpics.addEventListener(MouseEvent.CLICK, getURL);
    }
   
   getURL(buildPics, "content");

    ]]>
 </mx:Script>
	<mx:Image x="267" y="126" width="197" height="148" source="/instruments_link.jpg"/>
	<mx:Image x="415" y="49" source="/aboutus_link.jpg" width="300" height="92"/>
	<mx:Image x="191" y="289" source="/links_link.jpg" width="86" height="158"/>
	<mx:Image x="19" y="90" source="/neck_links.jpg" width="97" height="122"/>
	<mx:Image x="124" y="10" source="/contactus_link.jpg" width="202" height="137"/>
	<mx:Image x="150" y="166" source="/wood_links.jpg" width="68" height="197"/>
	<mx:Image x="506" y="149" source="/repairs_links.jpg" width="224" height="298"/>
	<mx:Image x="285" y="282" source="/buildpic_link.jpg" width="213" height="108"/>
	
/*This link button sits on top of the image at the same x y location, Giving the apearance that the image is clickable.
<mx:LinkButton x="285" y="282" id="buildPic" label="LinkButton" width="213" height="108" overSkin="@Embed('images/indexlinks/buildpic_link.jpg')"/>
	
</mx:Application>
