Big letters on the screen

Hi there,

I don't know what i did wrong.

This is my code and the screen. When i click on "trier", i can see only few big letters.

Tks forour help.

The second image is how i was suppose to get the list.

package {

import flash.display.*;

import flash.text.*;

import flash.events.MouseEvent;

import fl.controls.List;

public class U2A2_ElevesGestion extends MovieClip {

  var eleve:Array = new Array();

  var liste:String;

  public function U2A2_ElevesGestion() {

  btnLister.addEventListener(MouseEvent.CLICK, lister);

  btnTrier.addEventListener(MouseEvent.CLICK, trier);

  btnAjout.addEventListener(MouseEvent.CLICK, ajouter);

  btnSupprimer.addEventListener(MouseEvent.CLICK, supprimer);

  include "U2A2_ElevesListe.as"

  }

  function lister(event:MouseEvent):void {

  liste="";

  for (var i=0; i<eleve.length; i++)

  {

  liste = liste + ("Élève [" + i + "] : " + eleve + "\n");

  }

  affichage.text = liste;

  }

  function trier(event:MouseEvent):void {

  eleve.sort();

  }

  function ajouter(event:MouseEvent):void {

  eleve.push(txtSaisieNomEleve.text);

  }

  function supprimer(event:MouseEvent):void {

  var indiceEleve:int;

  indiceEleve =(eleve.indexOf(txtSaisieNomEleve.text));

  if (indiceEleve != -1)

  {

  for (var i=indiceEleve; i <eleve.length; i++)

  {

  eleve = eleve[i+1];

  }

  eleve.pop();

  }

  }

}

}
