Player Arm will not rotate when moving with Xbox Joystick

I have fixed it... well almost it still not 100% the way I like it but it dose pretty much what I wanted it to do.

Here's the updated code...

 public void CanTurn()
     {
         //Vector2 direction = Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position;
         //float angle = $$anonymous$$athf.Atan2(direction.y, direction.x) * $$anonymous$$athf.Rad2Deg;
         //Quaternion rotation = Quaternion.AngleAxis(angle, Vector3.forward);
         //transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Speed * Time.deltaTime);
         //Xboxcontroller...
         Vector2 shootingDirection = Vector2.right * -Input.GetAxis("Vertical Right") + Vector2.down * -Input.GetAxis("Horizontal Right");
         float angle = $$anonymous$$athf.Atan2(shootingDirection.y, shootingDirection.x) * $$anonymous$$athf.Rad2Deg;
         Quaternion rotation = Quaternion.AngleAxis(angle, Vector3.forward);
         transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Speed * Time.deltaTime);
     }
