Unity Networking, connecting to sever problems :(

[system]

Hey :) So ive been following a tutorial and have this code as working progress for networking and when i build the game and have run in background on, nothing happens. On one game it says server initialized and then when i try to join the game on the other it wont allow me to. any ideas of what im doing wrong?

var gameName: String ="Atomizer_Networking_Curtis";

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(){
	btnX = Screen.width * 0.1;
	btnY = Screen.width * 0.1; 
	btnW = Screen.width * 0.1; 
	btnH = Screen.width * 0.1;
} 

function startServer(){
	Network.InitializeServer(4, 25001, !Network.HavePublicAddress);
	MasterServer.RegisterHost(gameName,"Tutorial Game Name","This is a tutorial game"); 
}

function refreshHostList(){
	MasterServer.RequestHostList(gameName);
	refreshing = true;

}


function Update(){
	if(refreshing){
		if(MasterServer.PollHostList().Length > 0){
			refreshing = false;
			Debug.Log(MasterServer.PollHostList().Length);
			hostData = MasterServer.PollHostList();
		}
	}
}


// Messages

function OnServerInitialized(){
	Debug.Log("Server Initialized!");
}

function OnMasterServerEvent(mse:MasterServerEvent){
	if(mse == MasterServerEvent.RegistrationSucceeded){
		Debug.Log("Registered Server!");
	}
}

//GUI

function OnGUI(){
	if(!Network.isClient && !Network.isServer){
		if(GUI.Button(Rect(btnX, btnY, btnW, btnH), "Start")){
			Debug.Log("Starting Server");
			startServer();
		}
	
		if(GUI.Button(Rect(btnX, btnY * 1.2 + btnH, btnW, btnH), "Refresh")){
			Debug.Log("Refreshing");
			refreshHostList();
		}	
		
		if(hostData){
			for(var i : int = 0; i < hostData.length; i ++ ){
				if(GUI.Button(Rect(btnX * 1.5 + btnW, btnY * 1.2 + (btnH * i), btnW * 3, btnH * 0.5), hostData*.gameName));*

_ Network.Connect(hostData*);_
_ }_
_ }_
_ }_
_}*_

Your problem is most likely on line 69 in your code:

 if(GUI.Button(Rect(btnX * 1.5 + btnW, btnY * 1.2 + (btnH * i), btnW * 3, btnH * 0.5), hostData*.gameName));*

You have a semicolon at the end of the if statement, which means that Network.Connect is being called multiple times.
Remove the semicolon from the end of that line.
