Photon target character not connected

I'm using photon to make my game multiplayer and i want to control my character so on the "OnJoinedRoom()" function in my NetworkManager c# script i tell the camera to attach the newly spawned character to the "Target" Gameobject. It gets attached but i get an error: UnassignedReferenceException: The variable Target of characterMovementScript has not been assigned. You probably need to assign the Target variable of the characterMovementScript script in the inspector. characterMovementScript.Update () (at Assets/scripts/characterMovementScript.cs:30)

My script NetworkManager: using UnityEngine; using System.Collections;

 public class NetworkManager : Photon.MonoBehaviour {
 
     Vector3 vSpawn = new Vector3(0, 20, 0);
     // Use this for initialization
     void Start () {
         PhotonNetwork.ConnectUsingSettings ("alpha 0.1");
     }
 
     void OnGui(){
         GUILayout.Label(PhotonNetwork.connectionStateDetailed.ToString());
     }
 
     void OnJoinedLobby(){
         PhotonNetwork.JoinRandomRoom ();
     }
 
     void OnPhotonRandomJoinFailed(){
         PhotonNetwork.CreateRoom (null);
     }
 
     void OnJoinedRoom(){
         GameObject myCharacter = PhotonNetwork.Instantiate ("character", vSpawn, Quaternion.identity, 0);
         Camera.main.GetComponent<characterMovementScript> ().Target = myCharacter;
     }
     // Update is called once per frame
     void Update () {
     
     }
 }
 

relevant part of my characterMovementScript:

 public GameObject Target;
 ....
 Target.transform.position = Vector3.MoveTowards (Target.transform.position, targetPosition, Time.deltaTime * smooth);
