hi i need help were is my error? pls help me i don't now what to do.

pragma strict

private var chMotor : CharacterMotor (ScriptEngine)

private var superSprint : boolean = false; private var superJump : boolean = false; private var slowMo : boolean = false; private var hawkEye : boolean = false;

var mainCamera : Camera; var zoom : int = 20; var normal : int = 60; var smooth : float = 100;

var commands : Texture;

function Start() { chMotor = GetComponent(CharacterMotor); }

function Update() { //Super Jump if(Input.GetKeyDown("1")) { superJump = !superJump;

     if(superJump == true)
     {
         chMotor.jumping.baseHeight = 100;
         chMotor.movement.maxFallSpeed = 200;
     }
     
     else if(superJump == false)
     {
         chMotor.jumping.baseHeight = 10;
         chMotor.movement.maxFallSpeed = 20;
     }
 }
 
 //Super Speed
 if(Input.GetKeyDown("2"))
 {
     superSprint = !superSprint;
     
     if(superSprint == true)
     {
         chMotor.movement.maxForwardSpeed = 50;
         chMotor.movement.maxSidewaysSpeed = 50;
     }
     
     else if(superSprint == false)
     {
         chMotor.movement.maxForwardSpeed = 6;
         chMotor.movement.maxSidewaysSpeed = 6;
     }
 }
 
 //Slow Motion
 if(Input.GetKeyDown("3"))
 {
     slowMo = !slowMo;
     
     if(slowMo == true && Time.timeScale == 1.0)
     {
         Time.timeScale = 0.3;
     }
     
     else
         Time.timeScale = 1.0;
         Time.fixedDeltaTime = 0.02 * Time.timeScale;
 }
 
 //Hawk Eye
 if(Input.GetKeyDown("4"))
 {
     hawkEye = !hawkEye;
     
     if(hawkEye == true)
     {
         mainCamera.fieldOfView = Mathf.Lerp(mainCamera.fieldOfView, zoom, Time.deltaTime * smooth);
     }
     
     else if(hawkEye == false)
     {
         mainCamera.fieldOfView = Mathf.Lerp(mainCamera.fieldOfView, normal, Time.deltaTime * smooth);
     }
 }
