I started using Unity from yesterday and I have tried to script a gun to fire through java script and the bullets fire out sideways!? any help

Heres the Script

var BulletPrefab:Transform; var force : float = 6000;

function Update() { if(Input.GetButtonDown("Fire1")) { var bullet = Instantiate(BulletPrefab,

GameObject.Find("spawnPoint").transform.position,

GameObject.Find("Gun").transform.rotation);

bullet.rigidbody.AddForce(transform.forward * force);

} }
