Problem Displaying gameName when refreshing masterserver

I'm trying to start a simple server. I'm not getting any errors, the server starts, registers, and I can refresh and print 1 server is available.

The problem is when I try creating a GUIButton that prints the Game Name variable (after the server is created). The button fails to appear and I don't know why.

Here's the complete code (it runs), and I'm suspecting the problem is on the for loop, in the OnGUI Function. Thanks in advance.

 var buttonY : float;

var buttonW : float;

var buttonH : float;

function Start (){

 buttonX = Screen.width * 0.05;

 buttonY = Screen.width * 0.05;

 buttonW = Screen.width * 0.1; 

 buttonH = Screen.width * 0.1;

 

}

function startServer(){ //4

Network.InitializeServer(32,25001, !Network.HavePublicAddress);

MasterServer.RegisterHost(gameName,"Awesome Possum Server", "You'll be a boring cube.");

}

function refreshHostList(){ //5

 MasterServer.RequestHostList(gameName);

 refreshing = true;

 MasterServer.PollHostList();

 Debug.Log(MasterServer.PollHostList().Length);

 

}

function Update(){

 if(refreshing){

 

     if(MasterServer.PollHostList().Length > 0){

     

         refreshing = false;

         

         Debug.Log(MasterServer.PollHostList().Length);

         

         MasterServer.PollHostList();

     }

 

 }

}

// Messages

function OnServerInitialized(){ // 2

 Debug.Log("Server is up and ready...");

 

}

function OnMasterServerEvent(mse:MasterServerEvent){ //3

 if(mse == MasterServerEvent.RegistrationSucceeded){

 

     Debug.Log("Registered Server!");

 

 }

 

}

//GUI

function OnGUI(){ // 1

 if( GUI.Button(Rect(buttonX,buttonY,buttonW,buttonH),"Start Server") ){ 

 

     Debug.Log("Starting Server");

     

     startServer();

 

 }

 

 

 if( GUI.Button(Rect(buttonX,buttonY * 1.2 + buttonH,buttonW,buttonH),"Refresh Servers") ){ 

 

     Debug.Log("Refreshing Servers");

     

     refreshHostList();

 

 }

 

 if(hostData){

 

 for(var i:int = 0; i<hostData.length; i++){

 

     GUI.Button(Rect(buttonX * 1.5 + buttonW, buttonY*1.2 + (buttonH *i), buttonW*3, buttonH*0.5),hostData[i].gameName);

 }

 }
