GUI.box (Score counter) doesn't appear when game is on play.

Hey guys!

I have a problem. I am working on my last part of coding in Unity for a GUI score counter. Via a tutorial I came up with these codes:

(Script name: SugarBehavior = attached to the objects sugarhearts)

using UnityEngine; using System.Collections;

public class SugarBehavior : MonoBehaviour {

 void OnTriggerEnter(Collider collider)
 {
     switch(collider.gameObject.name)
     {
     case "Player":

         SugarController.sugarCount++;
         Destroy (this.gameObject);

         break;
     }
 }

}

(Script name: Sugarcontroller = attached to "empty object" SugarController)

using UnityEngine; using System.Collections;

public class SugarController : MonoBehaviour {

 public static int sugarCount = 0;

 void onGUI ()
 {
     //string sugarText = "Score: " + sugarCount;
     GUI.Box (new Rect(Screen.width - 150, 20, 130, 20), "Score: " + sugarCount);
     //GUI.Label (new Rect(Screen.width / 2 - 40, 300, 80, 30), "Score: " + sugerCount);
 }

}

Now the problem is that the "GUI.Box"/score doesn't appear when played. The objects are disappearing when touched though... I can't find what is wrong and I have no warnings or errors.
