Adding FPS to NavMesh Script

OK, using this generic code for enemies...problem is, the Unity 4.6 FPS character controller, can't be added to the enemy PreFab....it works if I add it in the hieracharcy....but won't work from a prefab, that I want to spawn.How do I fix this?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class navmesh : MonoBehaviour {
5.     NavMeshAgent agent;
6.     public Transform target;
7.  
8.     // Use this for initialization
9.     void Start () {
10.         agent = GetComponent<NavMeshAgent>();
11.             }
12.    
13.     // Update is called once per frame
14.     void Update () {
15.         agent.SetDestination(target.position);
16.     }
17. }

 

nevermind figured it out

Code (CSharp):

1. player = GameObject.FindGameObjectWithTag ("Player").transform;
