jump/shooting

Unity Engine
1

I made a script last week, move around,
but when i put the shooting, the jump stopped
working

what have i done wrong

var speed = 3.0;
var rotateSpeed  = 3.0; 
var bullitPrefab:Transform;
private var dead = false;
var tumbleSpeed = 800;
var decreaseTime = 0.01;
var decayTime = 0.01;
static var gotHit = false;
private var backup = [tumbleSpeed, decreaseTime, decayTime];

function LateUpdate()
{
		if(dead)
		{
			transform.position = Vector3(8,1,72);
			gameObject.Find("Main Camera").transform.position = Vector3(8,1,73);
			dead = false;
		}
		
		if(gotHit)
		{
				if(tumbleSpeed < 1)
				{
						tumbleSpeed = backup[0];
						decreaseTime = backup[1];
						decayTime = backup[2];
						gotHit = false;
				}
				else
				{
						transform.Rotate(0,tumbleSpeed * Time.deltaTime,0, Space.World);
						tumbleSpeed = tumbleSpeed-decreaseTime;
						decreaseTime += decayTime;
				}
				
		}
}

function OnControllerColliderHit(hit : ControllerColliderHit)
{
	  if(hit.gameObject.tag == "fallout")
	  {
			dead = true;
			//substract life here
			HealthControl.LIVES -= 1;
	  }
	  
	  if(hit.gameObject.tag == "enemyProjectile")
	  {
			gotHit = true;
	  }
}

function Update () 
{
	  var controller : CharacterController = GetComponent (CharacterController);
	  transform.Rotate (0, Input.GetAxis ("Horizontal") * rotateSpeed, 0);
	
	  var forward = transform. TransformDirection(Vector3.forward); 
	  var curSpeed = speed * Input.GetAxis ("Vertical"); 
	  
	  controller.SimpleMove (forward * curSpeed);
	  
	  if(Input.GetButtonDown("Jump"))
		
	  {
		  var bullit = Instantiate(bullitPrefab,
		                                 GameObject.Find("spawn").transform.position, 
										 Quaternion.identity);
		  bullit.rigidbody.AddForce(transform.forward * 2000);
	  }
} 

@script RequireComponent(CharacterController)

you have deleted the code that does the jumping.
