Why can't I set the Target

I'm trying to set the target of a homing shot after it's spawned when an enemy is hit by ray cast, but it doesn't work and I can't figure out why. It's suppose to set the enemy who's been placed into an Array.

 var SLT: Array = new Array();
 var Homing: GameObject;
 var current: int = 0;

 var slShot: GameObject = Instantiate(Homing, transform.position, Quaternion.identity);
 slShot.transform.GetComponent("Projectile").Target = SLT[current].transform;
 slShot.rigidbody.AddForce(transform.forward * 10, ForceMode.Impulse);

Here's the Projectile's script:

 static var Target: Transform;
 
 function Update(){
 
 
 transform.LookAt(Target);
 transform.position = Vector3.Lerp(transform.position, Target.position, Time.deltaTime * 10);
 Destroy(gameObject, 3);
 }
