Help!!!!!!! Need to walk sideways

I am making my fun game and can walk forward and turn with the mouse, but i can´t use a d to walk sideways.

Here is the script:


//Moving around
var speed = 3.0;
//Shooting
var bullitPrefab : Transform;
//Dying
static var dead = false;

//function OnControllerHit(hit: ControllerColliderHit)
function OnTriggerEnter(hit : Collider)
{
if(hit.gameObject.tag == "fallout")
{
dead = true;
//substract life here
HealthControl.LIVES -= 1;
}

if(hit.gameObject.tag == "enemyprojectile")
{
gothit = true;
HealthControl.HITS += 1;
Destroy(hit.gameObject);
}
}

function Update ()
{
var controller : CharacterController = GetComponent(CharacterController);

// Move forward / backward
var forward = transform.TransformDirection(Vector3.forward);
var curSpeed = speed * Input.GetAxis ("Vertical");
controller.SimpleMove(forward * curSpeed);

if(Input.GetButtonDown("Fire1"))
{
var bullit = Instantiate(bullitPrefab,
transform.Find("spawnpoint").transform.position,
Quaternion.identity);
bullit.tag ="wormProjectile";
bullit.rigidbody.AddForce(transform.forward * 2000);
}

}

function LateUpdate()
{
if(dead)
{
transform.position = Vector3(0, 1, 0);
gameObject.Find("Main Camera").transform.position = Vector3(0, 4, -10);
dead = false;
}
}

@script RequireComponent(CharacterController)


Please help!!!

 

transform.TransformDirection(Vector3.right;
transform.TransformDirection(Vector3.left);
