Make my camera turn smoothly

My script does that when i collide with a special gameobject, the camera points at the enemy. It all works but the camera just looks directly at the enemy, and does not turn slowly. How do i make it turn smoothly ?

var target : Transform;
var distance = 3.0;
var height = 3.0;
var damping = 5.0;
var smoothRotation = true;
var rotationDamping = 10.0;

function Update () 
	{	
		var wantedPosition = target.TransformPoint(0, height, -distance);
		transform.position = Vector3.Lerp (transform.position, wantedPosition, Time.deltaTime * damping);

		if (smoothRotation) {
			var wantedRotation = Quaternion.LookRotation(target.position - transform.position, target.up);
			transform.rotation = Quaternion.Slerp (transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
		}

		else transform.LookAt (target, target.up);
	}

Oh it didn’t take my script with, here is the script that i made:

#pragma strict

var target : Transform;
var look : boolean = false;

function OnTriggerEnter (other : Collider) {
if(other.tag == “Wall”)

GameObject.Find( “First Person Controller” ).GetComponent(FPSInputController).enabled = false;

GameObject.Find( “First Person Controller” ).GetComponent(CharacterMotor).enabled = false;

GameObject.Find( “First Person Controller” ).GetComponent(MouseLook).enabled = false;

GameObject.Find( “Main Camera” ).GetComponent(MouseLook).enabled = false;

look = true;

yield(WaitForSeconds(5));

GameObject.Find( “First Person Controller” ).GetComponent(FPSInputController).enabled = true;

GameObject.Find( “First Person Controller” ).GetComponent(CharacterMotor).enabled = true;

GameObject.Find( “First Person Controller” ).GetComponent(MouseLook).enabled = true;

GameObject.Find( “Main Camera” ).GetComponent(MouseLook).enabled = true;

look = false;

}

function Update ()
{

if(look == true)

transform.LookAt(target);

}
