find and chase a player

I want to have a monster spawn in game then chase the player, Only problem is i cant figure out how to get it to find the player while in game. I know how to do it though the hireachy.

var target : Transform; //This is what i need to do target=transform.Find("Player"); with, But i cant get it to work
var MoveSpeed = 7;
var MaxDist = 0;
var MinDist = 5;

var Health : float=150;

function Awake(){

}
function Update () 
{
	
	if(Health<=0){
		Destroy (gameObject);
	}
    transform.LookAt(target);
    if(Vector3.Distance(transform.position,target.position) >= MinDist){
         transform.position += transform.forward*MoveSpeed*Time.deltaTime;
 
 
 
         if(Vector3.Distance(transform.position,target.position) <= MaxDist)
             {
             
   } 
 
   }
}
function DoDamage(d){
	Debug.Log("FurryHit");
	Health-=d;
}

The script above WORKS, its just i want this prefab to spawn then chase the player. but again i cant get it to link and get the var target to be the player while in game.
how could i do this?

function Start()
{
target = GameObject.Find(“player”).transform;
}

You can use GameObject.Find() function to get the reference of any active object into the game.
just set your target = GameObject.Find("player").transform;

And make sure that your player must be active, otherwise Find() function will return null;
