So, I am Trying To make A temple run game and i am not able to jump or make it go side ways Please Help following is my Script

     public var speed = 10.0f; 
     var jumpSpeed = 20.0f;
  var gravity =20.0f;
  private var moveDirection = Vector3.zero;
  private var grounded :
  boolean = false; var coin = 0; var
      coinText = "coin: 0";
     var sideSpeed =12;
      
      function Start(){ // Set all
      animations to loop   
      animation.wrapMode = WrapMode.Loop;   
      // except shooting   
      animation["side"].wrapMode =
      WrapMode.Once;   
      animation["side"].layer = 1;   
      animation["jump"].wrapMode =
      WrapMode.Once;   
      animation["jump"].layer = 2;
      animation.Stop(); }
      
      
      function FixedUpdate() {
          if (grounded) {
          
          if (Mathf.Abs(Input.GetAxis("Vertical"))     <= 0.1){
             animation.CrossFade("run");
              
              }
              
           } 
                
               // We are grounded, so recalculate movedirection directly from axes
          moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
              moveDirection = transform.TransformDirection(moveDirection);
              moveDirection *= speed;
                if(Input.GetButtonDown("side")){
              animation.CrossFade("side");
              }
              
                if(Input.GetButtonDown("Jump")) {
      moveDirection.y = jumpSpeed; }
       
       
          if(Input.GetButtonDown("Jump")) {
       
          animation.CrossFade("jump");
          }
      
      // Apply gravity moveDirection.y -=
      gravity * Time.deltaTime;
      
      // Move the controller 
 `    `var controller
      : CharacterController =
      GetComponent(CharacterController); var
      flags = controller.Move(moveDirection
