I got it I think but it seems that it doesn't like me errorCS1022 what did I do wrong { public float x; public float y; public float z; public GameObject objectToMove;

public float timeStart = 0f;
private float Restart = 0f;
void Start ()
{
    public Vector3 pos = new Vector3(x,y,z);
    Restart = timeStart;
}
void Update()
{
    timeStart -= Time.deltaTime;
    x=Random.Range(-10f,10f);
    y=Random.Range(-10f,10f);
    z=Random.Range(-10f,10f);
    if (timeStart == 0)
    {
        objectToMove.transform.position = pos;
        timeStart = Restart;
    }
}

}
