Passing combobox var to loaded swf as3

Hi all, I've been building a world cup quiz. I have a combobox that loads a swf with the questions in. On the first swf the user chooses a country which loads a swf onto the stage which contains the questions. I cant work out how to pass the country name from the combobox to the new swf.

my ComboBox and swf load code is as follows:


package {
      
      
      import flash.events.*;
      import flash.display.*;
      import fl.controls.ComboBox;
      import fl.data.DataProvider;
      import flash.net.URLRequest;
      import flash.display.Loader;
      import flash.events.ProgressEvent;

      
      public class yahoo extends MovieClip {
      
                  private var bg:background_mc = new background_mc();
                  private var goal:goal_mc = new goal_mc();
                  private var soccerStars:soccerStars_mc = new soccerStars_mc();
                  /*private var replayBtn:replayBtn_mc = new replayBtn_mc();*/
                  private      var comboBox:ComboBox = new ComboBox();
      
      
                        public function yahoo() {
                              
                              stage.addChild(bg);
                              bg.x = 300;
                              bg.y = 300;
                              
                              stage.addChild(goal);
                              goal.x = 450;
                              goal.y = 180;
                              
                              stage.addChild(soccerStars);
                              soccerStars.x = 10;
                              soccerStars.y = 10;
                              
                              /*stage.addChild(replayBtn);
                              replayBtn.x = 580;
                              replayBtn.y = 40;
                              replayBtn.addEventListener(MouseEvent.MOUSE_DOWN, replay);*/
                              
                              stage.addChild(comboBox);
                              comboBox.x = 200;
                              comboBox.y = 300;
                              comboBox.dropdownWidth = 200;
                              comboBox.width = 200;
                              comboBox.prompt = "Select a nation";
                              comboBox.dataProvider = new DataProvider (worldcupNations);
                              comboBox.addEventListener(Event.CHANGE, changeHandler);
                              
                              
                        }
