Movie Clips Communicating

1 

var mainSiteListner:Object = new Object();
 var mainSite:MovieClipLoader = new MovieClipLoader();
 mainSiteListner.onLoadError = function() {
  throwError("Problem locating plug-in. Check location or path.  "+loc, "Plug-In Error");
 };
 mainSiteListner.onLoadInit = function() {
  statusText.text = "The main site has initialized.";
 };
 mainSiteListner.onLoadStart = function() {
  trace("Loading");
 };
 mainSiteListner.onLoadProgress = function(target, loaded, total) {
  trace("Loaded "+loaded+" of "+total);
 };
 mainSiteListner.onLoadComplete = function() {
  gotoAndStop(3);
  trace("Completed.");
 };
 mainSite.addListener(mainSiteListner);
 mainSite.loadClip(loc, 10);

This is how I am loading a clip into my movie…no problem there got it working…

Now when I unload the clip I want to make sure the main movie returns to frame 2…how could I achieve this?
