theres my code so far...But I am getting that error for the transform.find part. If I change it it works fine. thank you in advance.

var bulletPrefab:Transform;

function Awake()
{

}

function Update() 
{
    if(Input.GetMouseButtonDown(0))
    {
        Shoot();
    }
}

function Shoot()
{
        var bullet : GameObject = Instantiate(bulletPrefab , transform.Find("projRelease").transform.position ,Quaternion.identity);
        //ejectSound.Play();
        bullet.rigidbody.AddForce(transform.forward * 1000);
}
