how do i get rid of this error message

all im trying to do is get the camera moving with the player and i keep getting the error on unity im not sure on how to fix it because im new to unity and iv tried looking at other questions similar to this and i cant figure it out

error CS0120: An object reference is required to access non-static member `UnityEngine.GameObject.transform’

// Use this for initialization
void Start () {
    Player = GameObject.FindGameObjectWithTag("Player");
}

// Update is called once per frame
void lateUpdate () {
    float x = Mathf.Clamp(Player.transform.position.x, xmin, xmax);
    float y = Mathf.Clamp(Player.transform.position.y, ymin, ymax);
    GameObject.transform.position = new Vector3 (x, y, GameObject.transform.position.z);
}

}

Change

GameObject.transform.position = new Vector3 (x, y, GameObject.transform.position.z);

to

transform.position = new Vector3 (x, y, transform.position.z);
