	private InputField[] inputArray;
	// Use this for initialization
	void Start () {
		system = EventSystem.current;
		inputArray = this.GetComponentsInChildren<InputField>();
	}
	int index = 0;
	// Update is called once per frame
	void Update () {
		if (Input.GetKeyDown(KeyCode.Tab))
		{
			if (index>=inputArray.Length)
				index = 0;

			system.SetSelectedGameObject(inputArray[index].gameObject,new BaseEventData(system));
