Cannot Drag GUIText gameobject unto Inspector.

I have some code that should let me drag a GUItext gameobject unto the inspector so I can keep count after each object is destroyed. The Count should go up by 1 for each object destroyed by my rockets.

using UnityEngine;
using System.Collections;

public class CountDestroy : MonoBehaviour {

public int Count;
public GUIText countText;

void Start(){
	Count = 0;
	countText.text = "Count:" + Count.ToString();
}

void FixedUpdate () {
	
	if (rigidbody.velocity.magnitude > 12){
		
		Destroy(gameObject,1); 
		Count++;
		countText.text = "Count:" + Count.ToString();
		

	}
	
}

}

At the top of your class, make sure you also use

using UnityEngine.UI;

Then, make countText a Text object instead of GUIText, like so:

public Text countText;

Then the inspector should allow you to drag the game object into the spot for countText;
