Form and Buttons within External SWF not working when loaded

I’m currently working on a flash site, which consists of a “Main” SWF file that has buttons to load external SWF files. I figured out how to make the external SWF files show on its own layer below other layers on the main time line of the Main SWF. I created a blank movie clip file on it’s own layer of the main time line and used this to call out to it:

this.mySWFLoadingClip.addChild(loader);

This worked perfectly. The website so far works perfectly with each page of the website being an externally loaded SWF. The problem I came across today though, is that buttons and text fields within the external SWF files don’t work when they are loaded onto the “Main” SWF. They only work when I open the external SWF files individually. I really need to figure out how to make buttons and the text fields within the external SWF files when loaded onto the “MAIN” SWF. I first came across this problem when I tried adding a form that I created to one of the external SWF files called guestlist_page_swf.swf. The form works on its own when I open that SWF individually, but when I try to load that SWF file with the form as a page on my “Main” SWF, the mouse doesn’t even recognize that the submit button is a button, and it doesn’t allow me to click on the text fields. If you can help me understand how to make this work, I would be very grateful. Here is the link to the site I am having the problem with, and the problem page is the Guest List page:

Below is the code from my Main SWF file and the External SWF file with the form on it:

MAIN SWF:

var Xpos:Number = 0.0;
var Ypos:Number = 192.5;
var swf:MovieClip;
var loader:Loader = new Loader();

var defaultSWF:URLRequest = new URLRequest(“swfs/home_page_swf.swf”);

loader.load(defaultSWF);
loader.x = Xpos;
loader.y = Ypos;
this.mySWFLoadingClip.addChild(loader);
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

// Btns Universal function
function btnClick(event:MouseEvent):void {

this.mySWFLoadingClip.removeChild(loader);
var newSWFRequest:URLRequest = new URLRequest(“swfs/” + event.target.name + “.swf”);
loader.load(newSWFRequest);
loader.x = Xpos;
loader.y = Ypos;
this.mySWFLoadingClip.addChild(loader);
}
// Btn listeners
home_page_swf.addEventListener(MouseEvent.CLICK, btnClick);
