Have null errors

I have a simple two codes to move object to spots. But i have two null errors,at start of the game : NullReferenceException at : follower = GameObject.Find (“Follower”).GetComponent< Follower >(); and second when im clicking at the object with a script Leaders :NullReferenceException: Object reference not set to an instance of an object at : follower.v3Dest = transform.position; Thank for any help!
public class Follower : MonoBehaviour
{

public Vector3 v3Dest;
public float speed = 5.0f;

void Start () {
v3Dest = transform.position;
}

void Update () {
transform.position = Vector3.MoveTowards(transform.position,v3Dest,Time .deltaTime * speed);
transform.LookAt(v3Dest);
}
}
And this script goes on any leaders (i.e. the things you click on to change the destination):

public class Leaders : MonoBehaviour {

private Follower follower;

void Start () {
follower = GameObject.Find (“Follower”).GetComponent< Follower >();
}

void OnMouseDown() {
follower.v3Dest = transform.position;
}
}

Please use code tags. http://forum.unity3d.com/threads/143875-Using-code-tags-properly
Do you have a game object in the scene with the name ‘Follower’? It needs to spell exactly as that with the capital letter and everything. Your null error is probably pointing at GameObject.Find since it failed to find the object you want (hence returning null). The second one points at follower variable because the GameObject.Find returned null and you assigned that to the follower variable.

Thank,you were right i forgot to name my cube. Thanks!

Please do not double post!
