Problem with UFPS and photon

Hi guys, so i was working on a multiplayer fps with UFPS and photon network, everything seems to be good until I disable the Vp_FPController and FPSCamera components and enable them only for “my” player instance.
So i wrote this :

    void SpawnPlayer()
    	{
    		GameObject PlayerGO = PhotonNetwork.Instantiate("PlayerPrefab", new Vector3(1000,0,1000), Quaternion.identity, 0);
    		Vp_FPController controllerGO = PlayerGO.GetComponent<Vp_FPController>();
        	controllerGO.enabled = true;
       	 	FPSCamera cameraGO = PlayerGO.GetComponent<FPSCamera>();
        	cameraGO.enabled = true;
    	}

I got those errors

Assets/Scripts/NetWorkManager.cs(47,17): error CS0246: The type or namespace name Vp_FPController' could not be found. Are you missing a using directive or an assembly reference? Assets/Scripts/NetWorkManager.cs(49,17): error CS0246: The type or namespace name FPSCamera’ could not be found. Are you missing a using directive or an assembly reference?

Any solution ? thanks.

void SpawnPlayer()
{
GameObject PlayerGO = PhotonNetwork.Instantiate(“PlayerPrefab”, new Vector3(1000,0,1000), Quaternion.identity, 0);
if(PhotonView.isMine == true)
{
Vp_FPController controllerGO = PlayerGO.GetComponent<Vp_FPController>();
controllerGO.enabled = true;
FPSCamera cameraGO = PlayerGO.GetComponent();
cameraGO.enabled = true;
}
else if(photonView.isMine == false)
{
Vp_FPController controllerGO = PlayerGO.GetComponent();
controllerGO.enabled = false;
FPSCamera cameraGO = PlayerGO.GetComponent();
cameraGO.enabled = false;
}
}
