Simple move script

I consider myself experienced with Unity somewhat, but lately I have been working on other stuff and I'm super rusty. Why isn't this simple move script working? I dont understand.

 enter code here

var forwardSpeed : float = 5;

var strafeSpeed : float = 2;

static var moveX : float = 0;

static var moveZ : float = 0;

private var moveDirection : Vector3 = Vector3.zero;

function Start () {

}

function Update () {

var controller : CharacterController = transform.GetComponent(CharacterController);

if(controller.isGrounded) {

moveX = Input.GetAxis("Horizontal") strafeSpeed; moveZ = Input.GetAxis("Vertical") forwardSpeed;

moveDirection = Vector3(moveX, 0, moveZ); moveDirection = transform.TransformDirection(moveDirection);

}

controller.Move(moveDirection * Time.deltaTime);

}
