Add a wave to a Translate

Hi,

im new on unity, and on game programming. I'm trying to make a translate of a missile a little more than a simple transform.forward, im trying to add two waves on x and y axies.

here is the working code:

function Update () {

 transform.Translate(Vector3.forward*60*Time.deltaTime);

}

here is the wrong code:

private var player:GameObject;

player=gameObject.Find("Player");

private var distanceToPlayer:float;

distanceToPlayer=Vector3.Distance(transform.position,player.transform.position);

private var numIteration:float;

numIteration=1;

private var waveHeight:float;

waveHeight=1;

private var ondex:float;

private var ondey:float;

function Update () {

 var ondex=waveHeight*Mathf.Sin((transform.position.x/distanceToPlayer)*Mathf.PI*numIteration);
 var ondey=waveHeight*Mathf.Sin((transform.position.y/distanceToPlayer)*Mathf.PI*numIteration);
 transform.Translate(ondex,ondey,Vector3.forward*60*Time.deltaTime,Space.World);

}

Can you help me? Thx
