Repeating a texture?

Trying to venture into UnityGUI here and I'm trying to attempt a Healthbar similar to the Old Mega-Man X.

^^For those who don't know what it is^^

No-matter what I try, the sprite is always drawn in the middle of the box.

 using UnityEngine;
 using System.Collections;
 
 public class GUIManager : MonoBehaviour 
 {
     public Texture aTexture;
     private float maxHealth;
     private float currHealth;
 
     private float TopHUDHeight = 608;
     private float HUDHeight = 162;
     
     void Start()
     {
         maxHealth = 100f;
         currHealth = maxHealth;
         aTexture.wrapMode = TextureWrapMode.Repeat;
     }
     
     void Update()
     {
         currHealth = 100f;
     }
     
     void OnGUI()
     {
         GUI.Box(new Rect(0,  TopHUDHeight, Screen.width, HUDHeight), "");
         GUI.Box (new Rect(0, TopHUDHeight, 240, HUDHeight), "Inventory/Money");
         GUI.Box (new Rect(241, TopHUDHeight,25, HUDHeight), "H\nE\nA\nL\nT\nH");
         GUILayout.BeginVertical();
         GUI.DrawTexture(new Rect(241, TopHUDHeight, 25, HUDHeight), aTexture, ScaleMode.ScaleToFit);
         GUILayout.EndVertical();
         GUI.Box (new Rect(267, TopHUDHeight, 490, HUDHeight), "Chat");
         GUI.Box (new Rect(758,TopHUDHeight,25, HUDHeight), "E\nX\nP");
         GUI.Box (new Rect(784, TopHUDHeight, 240, HUDHeight), "Gun/Ammo");    
                 
     }
     
 }
