What is wrong with this scoreboard?

I am trying to create a scoreboard for multiplayer. I want the scoreboard to track player's name, kills, death and ping. I also want the server to be able to kick players using this. This will provide the framework for kicking and a scoreboard. Here is the code:

 #pragma strict
 
 import System.Text.RegularExpressions;
 
 //Strings
 private var Username : String;
 private var players : String[];
 private var pings : String[];
 
 //Ints
 private var myConnection : int = -1;
 private var i : int = 0;
 private var a : int = 0;
 private var kills : int[];
 private var deaths : int[];
 
 //Boolean
 private var showScoreboard : boolean = false;
 
 //KeyCodes
 var toggleKey : KeyCode = KeyCode.Tab;
 
 //NetworkPlayers
 var connections : NetworkPlayer[];
 
 function Start()
 {
     Username = PlayerPrefs.GetString("Username", "Guest");
     if (Network.isServer)
     {
         connections = Network.connections;
         ServerConfig();
     }
     if (Network.isClient)
     {
         if (myConnection == -1 && Network.isClient)
         {
             for (a = 0; a < connections.Length; a++)
             {
                 if (connections[a] == networkView.owner)
                 {
                     myConnection = a + 1;
                     networkView.RPC("TellScoreboardName", RPCMode.All, Username, myConnection);
                 }
             }
         }
     }
 }
 
 function Update()
 {
     if (myConnection == -1 && Network.isClient)
     {
         for (a = 0; a < connections.Length; a++)
         {
             if (connections[a] == networkView.owner)
             {
                 myConnection = a + 1;
                 networkView.RPC("TellScoreboardName", RPCMode.All, Username, myConnection);
             }
         }
     }
     if (Input.GetKeyDown(toggleKey))
     {
         showScoreboard = true;
     }
     if (Input.GetKeyUp(toggleKey))
     {
         showScoreboard = false;
     }
 }
 
 function OnGUI()
 {
     if (showScoreboard && Network.isServer)
     {
         GUI.Window(0, Rect(Screen.width /4, Screen.height/4, Screen.width /2, Screen.height/2), Scoreboard, "Scoreboard");
     }
 }
 
 function Scoreboard(windowID : int)
 {
     GUI.Label(Rect(5,30,250,25), "Name");
     GUI.Label(Rect(260,30,50,25), "Kills");
     GUI.Label(Rect(315,30,50,25), "Deaths");
     GUI.Label(Rect(370,30,100,25), "Ping (Avg)");
     for (var PL : int = 0; PL < players.Length; PL++)
     {
         GUI.Label(Rect(5,60 + (25 * PL),250,25), players[PL]);
     }
     /*for (i = 0; i < kills.Length; i++)
     {
         GUI.Label(Rect(260,60 + (25 * i),50,25), kills[i].ToString());
     }
     for (i = 0; i < deaths.Length; i++)
     {
         GUI.Label(Rect(315,60 + (25 * i),50,25), deaths[i].ToString());
     }
     for (i = 0; i < connections.Length; i++)
     {
         GUI.Label(Rect(370,60 + (25 * (i + 1)),100,25), Network.GetAveragePing(Network.connections[i + 1]) + "ms");
     }*/
     if (Network.isServer && connections.Length > 0)
     {
         for (var PK = 0; PK < (connections.Length + 1); PK++)
         {
             if(GUI.Button(Rect(425, 50 + (25 * (PK + 1)), 100,25), "Kick"))
             {
                 networkView.RPC("KickPlayer", RPCMode.AllBuffered, PK, connections[i]);
                 Network.CloseConnection(connections[i], true);
             }
         }
     }
 }
 
 function ServerConfig()
 {
     var tempIntNoPlayers : int = GameObject.FindGameObjectWithTag("MainCamera").GetComponent(NetworkManager).NoOfPlayers;
     players = new String[tempIntNoPlayers + 1];
     kills = new int[tempIntNoPlayers + 1];
     deaths = new int[tempIntNoPlayers + 1];
     pings = new String[tempIntNoPlayers + 1];
     players[0] = Username;
     kills[0] = 0;
     deaths[0] = 0;
     pings[0] = "0";
 }
 
 @RPC
 function ScoreboardUpdate(pls : String, info : NetworkMessageInfo)//, kls : int[], dts : int[], png : String[])
 {
     var stringArray : String[] = Regex.Split(pls, "-");
     
     players = stringArray;
     /*kills = kls;
     deaths = dts;
     pings = png;*/
 }
 
 @RPC
 function TellScoreboardName(pl : String, connectionInt : int, info : NetworkMessageInfo)
 {
     if (Network.isServer)
     {
         players[connectionInt] = pl;
     }
 }
 
 @RPC
 function KickPlayer(playerNo : int, player : NetworkPlayer)
 {
     if (Network.isServer)
     {
         GameObject.FindGameObjectWithTag("MainCamera").GetComponent(FPSChat).addGameChatMessage(players[playerNo]+" was kicked from the game");
     }
 }

Any suggestions will help. Cheers,
