Java code not working. LOST PROJECT

Okay so I was just making a game i spent alot of time on it and saddy i deleted it on accident so I was trying to type my long script over again and it is not working. here is the code:

 var Glock17   : GameObject;
 
 var Glock17Aim    : GameObject;
 
 private var ShowMenu = false;
 
 private var Rank = 0;
 private var Kills = 0;
 private var EXP = 0;
 private var Wave = 0;
 
 function Start () {
     Glock17.SetActive(true);
     Glock17Aim.SetActive(false);
 }
 
 function Update () {
 
      if(Input.GetMouseButtonDown(1)) {
     Glock17.SetActive(false);
     Glock17Aim.SetActive(true);
     }
     if(Input.GetMouseButtonUp(1)) {
     Glock17.SetActive(true);
     Glock17Aim.SetActive(false);
     }
     
     ShowMenu = true;
     if(ShowMenu == false) {
     if(Input.GetKeyDown ("space")) {
         ShowMenu = true;
     }
     }
     if(ShowMenu == true) {
     if(Input.GetKeyUp ("space")) {
         ShowMenu = false;
     }
     }
 }
 function OnGUI() {
     
     if(ShowMenu == true) {
         GUI.Box (Rect(0, 0, 640, 480), "Pop Up" );
         GUI.Box (Rect(0, 0, 640, 480), "Pop Up" );
 
         GUI.Box (Rect(0, 0, 150, 480), "Stats" );
         GUI.Box (Rect(0, 0, 150, 480), "Stats" );
         
         GUI.Box (Rect(200, 0, 130, 130), "" );
         GUI.Label (Rect(0, 0, 130, 130), "Wave:" + Wave );
     
     
     }
 }

Some of the GUI stuff dont work. and the vars dont. Sigh well thanks :(
