Configure AS3 dropdown into existing project

OK, I got the first part to work, used a different dropdown but now my problem is the original AS calls the green

see red  blue and green below

var Xpos:Number = 0;
var Ypos:Number = 0;
var swf:MovieClip;
var loader:Loader = new Loader();

var defaultSWF:URLRequest = new URLRequest("swfs/home.swf");

loader.load(defaultSWF);
loader.x = Xpos;
loader.y = Ypos;
addChild(loader);
//////////////////////////////////////////////////////////////////////  //////////////////////////////////////////////////////////
// Btns Universal function
function btnClick(event:MouseEvent):void {

    SoundMixer.stopAll();
    removeChild(loader);
    var newSWFRequest:URLRequest = new URLRequest("swfs/" + event.target.name + ".swf");
    loader.load(newSWFRequest);
    loader.x = Xpos;
    loader.y = Ypos;
    addChild(loader);
}

   
// Btn listeners
home.addEventListener(MouseEvent.CLICK, btnClick);
commercial.addEventListener(MouseEvent.CLICK, btnClick);
menu.addEventListener(MouseEvent.CLICK, btnClick);
videomontage.addEventListener(MouseEvent.CLICK, btnClick);
contact.addEventListener(MouseEvent.CLICK, btnClick);

DROPDOWN ACTIONSCRIPT IN MOVIECLIP

menu.addEventListener(MouseEvent.CLICK, btnClick);

function btnClick(event:MouseEvent):void {
var main1URL:URLRequest = new URLRequest("http://www.adobe.com");
navigateToURL(main1URL, "_self");
}

/////////////////////////////////////////     END REFERENCE CLICK CODE    ///////////////////////////////////////////

// Event Listeners for all 3 main buttons
menu.addEventListener(MouseEvent.ROLL_OVER, main1Over); button now has two functions
/*
mainBtn2.addEventListener(MouseEvent.ROLL_OVER, main2Over); I have two d downs so i would name these menu1 / menu2?
mainBtn3.addEventListener(MouseEvent.ROLL_OVER, main3Over);

// ROLL_OVER fuctions for all 3 main buttons
function main1Over(event:MouseEvent):void {
gotoAndPlay("down1");
}I would need to add the original function for these or re name? to call the swfs (above in green),

function main2Over(event:MouseEvent):void {
gotoAndPlay("down2");
}
/*
function main3Over(event:MouseEvent):void {
gotoAndPlay("down3");
}
*/

You can probably just add it as you show it, all in the same frame.  Then give your menu the instance name "menu".
