Reload FPS Animation Not Playing (Javascript)

Ok so i have my shoot script and everything works fine but when i reload it plays first couple frames then cuts. then has 3.3 reload time and adds bullets back but without the animation.

 //Gun Stats
 
 var Damage : float;
 var Range : float = 1000;
 var Force : float = 500;
 var Clips : int = 2;
 var BulletsPerClip : int = 12;
 var ReloadTime : float = 3.3;
 var BulletsLeft : int = 0;
 var ShootTimer : float = 0;
 var ShootCooler : float = 0.6;
 public var ShootAudio : AudioClip;
 public var ReloadAudio : AudioClip;
 var Aiming: boolean = false;
 var Gun : GameObject;
 
 function Start(){
 
     BulletsLeft = BulletsPerClip;
     
 
 }
 
 
 function Update () {
     
     if (ShootTimer > 0){
         ShootTimer -= Time.deltaTime;
     }
     
     if(ShootTimer < 0){
         ShootTimer = 0;
     }
     
     if(Input.GetMouseButtonDown(0) && BulletsLeft)
     {
         if(ShootTimer ==0){
             RayShoot();
             PlayShootAudio();
             ShootTimer = ShootCooler;
         }
     }
 
     if (Input.GetMouseButtonUp(1))
     {
         Aiming = false;
     }
     
         if (Input.GetMouseButtonDown(1))
     {
         Aiming = true;
     }
 }
 
 function RayShoot () {
     if(Aiming == true){
         Gun.animation.Play("ShootingAiming");
     }
     
     else if(Aiming == false){
     
         Gun.animation.Play("ShootingIdle");
     }
     var Hit : RaycastHit;
     var DirectionRay : Vector3 = transform.TransformDirection(Vector3.forward);
     
     Debug.DrawRay(transform.position, DirectionRay * Range, Color.blue);
     if(Physics.Raycast(transform.position , DirectionRay , Hit , Range)){
         
         if(Hit.rigidbody) {
             Hit.rigidbody.AddForceAtPosition(DirectionRay * Force, Hit.point);
         }
     }
 
     BulletsLeft --;
     
     if(BulletsLeft <0){
         BulletsLeft = 0;
     }
     
     if(BulletsLeft == 0){
         Reload();
     }
 }
 
 
 function Reload() {
     PlayReloadAudio();
     Gun.animation.Play("Reload", PlayMode.StopAll);
     yield WaitForSeconds(ReloadTime);
     if(Clips > 0){
     
         BulletsLeft = BulletsPerClip;
     }
 }
 
 function PlayShootAudio(){
     audio.PlayOneShot(ShootAudio);
 }
 
 function PlayReloadAudio(){
     audio.PlayOneShot(ReloadAudio);
