Project #00: Roll-a-Ball - unable to change properties

I just noticed something and this is after adding a Speed property to the script. I can scroll with my cursor over the Speed text(the arrows going both ways show) but I cannot just go into the text box to change it. This appears also to be the case for the rigidbody section ,sphere collider but not the transform area…those I can hi-lite and I see blue.Other ones I mentioned I can’t get that to appear.I am not sure exactly why this is ocurring and wondered if anyone else had an issue like this occur.

If you want to edit a textField, you need to declare a string, and define it in your OnGUI code.

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour
{
	string textFieldString = "";
	
	void OnGUI()
	{
	    textFieldString = GUI.TextField(new Rect(0, 0, 256, 64), textFieldString);
	}
}
