Problem in loading and saving the game

Hello all,

While making save game script i took the following attributes

1)Current level name 2)player location and ammo count

while loading I loaded the saved level name and set the player location and ammo. And its working properly but the loaded game is not lasting even for a second and the level with the default settings and variables.

Here is the code:

 import System.IO;
 
 private var buttonWidth : int;
 private var buttonHeight : int;
 private var groupWidth : int;
 private var groupHeight : int;
 var paused : boolean;
 var character : GameObject;
 var shootObject : GameObject;
 var xpos : float;
 var ypos : float;
 var zpos : float;
 function Start () 
 {
     buttonWidth = 200;
     buttonHeight = 50;
     groupWidth = 200;
     groupHeight = 500;
     Screen.lockCursor = true;
     Time.timeScale = 1;
     paused = false;
     //shootObject = GameObject.FindGameObjectWithTag("Gun");
 }
 function OnGUI()
 {
     if(paused)
     {
         GUI.BeginGroup(new Rect(((Screen.width/2) - (groupWidth/2)), ((Screen.height/2) - (groupHeight/2)), groupWidth, groupHeight));
         if(GUI.Button(new Rect(0, 0, buttonWidth, buttonHeight),"Main Menu"))
         {
             Application.LoadLevel(0);
         }
         if(GUI.Button(new Rect(0, 60, buttonWidth, buttonHeight),"Save Game"))
         {
             var path : String = "C:/Aditya/TestSaves";
             if (!Directory.Exists(path))
             {
                 Directory.CreateDirectory(path);
             }
             if(!File.Exists(path + "/SaveSlot1.txt"))
             {
                 var create_text = File.CreateText(path + "/SaveSlot1.txt");
                 create_text.Close();
             }
             var loadedfile = new StreamWriter(path + "/SaveSlot1.txt");
             loadedfile.WriteLine(saveData());
             loadedfile.Close();
         }    
         if(GUI.Button(new Rect(0, 120, buttonWidth, buttonHeight),"Load Game"))
         {
             loadData();
         }
         if(GUI.Button(new Rect(0, 180, buttonWidth, buttonHeight),"Quit"))
         {
             Application.Quit();
         }
         GUI.EndGroup();
     }
 }
 function Update () 
 {
     if(Input.GetKeyUp(KeyCode.Escape))
     {
         if(Time.timeScale == 0)
         {
             GameObject.Find("First Person Controller").GetComponent(MouseLook).enabled = true;
             Screen.lockCursor = true;
             Time.timeScale = 1;
             paused = false;
         }
         else
         {
             GameObject.Find("First Person Controller").GetComponent(MouseLook).enabled = false;
             Screen.lockCursor = false;
             Time.timeScale = 0;
             paused = true;
         }
     }
 }
 
 function saveData()
 {
     var data : String;
     xpos = character.transform.position.x;
     ypos = character.transform.position.y;
     zpos = character.transform.position.z;
     data += "LevelName:" + Application.loadedLevelName + "\n";
     data += "X-Position:" + xpos.ToString() + "\n";
     data += "Y-Position:" + ypos.ToString() + "\n";
     data += "Z-Position:" + zpos.ToString() + "\n";
     data += "Ammo:" + shootObject.GetComponent(shoot).ammo + "\n";
     
     return data;
 }
 
 function loadData()
 {
     var path : String = "C:/Aditya/TestSaves";
     if(File.Exists(path + "/SaveSlot1.txt"))
     {
         var loadeddata = File.OpenText(path + "/SaveSlot1.txt");
         var readdata = loadeddata.ReadLine();
         while(readdata != null)
         {
             var getdata = readdata.ToString().Split(":" [0]);
             //if(getdata[0] == "LevelName") Application.LoadLevel(getdata[1]);
             if(getdata[0] == "X-Position") character.transform.position.x = float.Parse(getdata[1]);
             if(getdata[0] == "Y-Position") character.transform.position.y = float.Parse(getdata[1]);
             if(getdata[0] == "Z-Position") character.transform.position.z = float.Parse(getdata[1]);
             if(getdata[0] == "Ammo") shootObject.GetComponent(shoot).ammo = float.Parse(getdata[1]);
             readdata = loadeddata.ReadLine();
         }
         loadeddata.Close();
     }    
 }

Someone help me as soon as possible.

Thanks, Aditya
