Cardboard and Navmesh: Problem with Player Movement

Hi guys, i have a problem in my script. The idea of my game is make the player walk only on determined "Walkpoints". But when i click on my Walkpoint, the player goes directly to the last Walkpoint that have on the scene. What i have to do to player go on the order that i want? Already, grateful

My script:

[RequireComponent(typeof(Collider))]

public class Move : MonoBehaviour{ //IGvrGazeResponder {

 private Vector3 goal;
 public NavMeshAgent agent;
 public GameObject cursor;
 private GameObject wp;

 void Start() 
 {
     agent = GetComponent<NavMeshAgent> ();
     wp = GameObject.FindGameObjectWithTag("WalkPoint");
     goal = wp.transform.position;
 }

 public void PlayerMove()
 {
     goal = cursor.transform.position;

     MoveToDestination ();
 }

 public void MoveToDestination()
 {
     agent.destination = goal;
     Debug.Log ("Move");
 }

 #region IGvrGazeResponder implementation

 public void OnGazeTrigger() 
 {
     PlayerMove();
 }

 #endregion

}
