Help with a simple following AI

So I have been working on a basic javascript code that makes an object, in my case a zombie, look at and follow another object, the Player. For some reason this code is pulling the error:
"‘transform’ is not a member of ‘Object’. "

Any ideas? Here is my code:

#pragma strict

var speed = .7;
var target;

function Start () {

target = GameObject.Find("Player");


function Update () {

	transform.position += transform.forward * speed * Time.deltaTime;


replace “var target” with “var target : GameObject”
