Networkmanager errors and gui to small

Hello, I have followed Cg_cookie's tutorial on networking, But first i noticed that my GUI did not show up and I was never able to try if it worked because i always got errors. If someone here got time it would be nice if you could help me. Here's the errors [Note: I'm not hundered if I wrote it right because I never tried it because of errors]

And here's the tutorial http://vimeo.com/33996023

And here's the Code I tried to copy

 var playerPrefab:GameObject;
 var SpawnObject: Transform;
 var gameName:String = "Trackants";
 
 private var refreshing:boolean;
 private var hostData : HostData[];
 
 private var btnX : float;
 private var btnY : float;
 private var btnW : float;
 private var btnH : float;
  
  function Start(){
     bntX = Screen.width * 0.05;
     bntY = Screen.height * 0.05;
     bntW = Screen.width * 0.1;
     bntH = Screen.width * 0.1;
 }
  
  function   startServer(){
   Network.InitializeServer(32,25000, !Network.HavePublicAddress);
   MasterServer.RegisterHost(gameName, "Trackant game", "This is a co-op game!");
 }
 
 function  refreshHostList(){
   MasterServer.RequireHostList(gameName);
   refreshing = true;
 
   Debug.Log(MasterServer.PollHostList().Length);
 }
 
 function Update(){
   if(refreshing){
     if (MasterServer.PollHostList().Length <0){
     refreshing = false;
     Debug.Log(MasterServer.PollHostList().Length);
     hostData=MasterServer.PollHostList();
      }
   }
 }
 
 function SpawnPlayer(){
 Network.Instantiate(playerPrefab, spawnObject.position, Quaternion.identity,0);
 }
 function OnConnectedToServer(){
   spawnPlayer();
 
 //Messages
 function OnServerInitialized(){
  Debug.Log("Server initialized!");
  spawnPlayer():
 }
 
 
 
   function OnMasterServerEvent(mse:MasterServerEvent){
     if(mse == MasterServerEvent.RegistrationSucceeded){
       Debug.Log("Redistered Server!");
 
     }
 }
   function OnGUI(){
     if(Network.isClient && !Network.isServer ){
       if(GUI.Button(Rect(btnX, btnY, btnW, btnH), "Start server")){
       Debug.log("starting server");
       startServer();
       }
         if(GUI.Button(Rect(btnX, btnY * 1.2 + btnH, btnW, btnH), "Refresh hosts")){
          Debug.log ("refreshing");
          refreshHostList();
       }
       
       if(hostData){
       for(var i:int = 0; i<hostData.lenght; int++){
       if (GUI.Button(Rect(btnX *1.5 + btnW, btnY*1.2 + (btnH * i), btnW*3, btnH*.5), hostData[i].gameName));
         Network.Connect(hostData[i]);
       }
      }
     }
    }
