My GUI HUD isn't showing up?!?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections.Generic;
3.  
4. public class HUD : MonoBehaviour {
5.     public GUISkin resourceSkin, ordersSkin;
6.     private const int ORDERS_BAR_WIDTH = 150, RESOURCE_BAR_HEIGHT = 40;
7.     private Player player;
8.  
9.  
10.     void Start () {
11.         player = transform.root.GetComponent<Player>();
12.     }
13.  
14.    
15.     void OnGUI () {
16.         if(player.human) {
17.             DrawOrdersBar();
18.             DrawResourceBar();
19.         }
20.     }
21.     private void DrawOrdersBar() {
22.         GUI.skin = ordersSkin;
23.         GUI.BeginGroup(new Rect(Screen.width-ORDERS_BAR_WIDTH,RESOURCE_BAR_HEIGHT,ORDERS_BAR_WIDTH,Screen.height-RESOURCE_BAR_HEIGHT));
24.         GUI.Box(new Rect(0,0,ORDERS_BAR_WIDTH,Screen.height-RESOURCE_BAR_HEIGHT),"");
25.         GUI.EndGroup();
26.     }
27.     private void DrawResourceBar() {
28.         GUI.skin = resourceSkin;
29.         GUI.BeginGroup(new Rect(0,0,Screen.width,RESOURCE_BAR_HEIGHT));
30.         GUI.Box(new Rect(0,0,Screen.width,RESOURCE_BAR_HEIGHT),"");
31.         GUI.EndGroup();
32.         }
33. }

PLEASE HELP!

 

1) Is the script attached to an object?

2) have you confirmed that Player.human is true?

3) Any error messages?
