Can't draw a box using Basic GUI

Very… VERY… Basic script… I mean… Come on…

using UnityEngine;
using System.Collections;

public class StatPoints : MonoBehaviour {
	void OnGUI() {
		 GUI.Box(new Rect(10, 20, 20, 20), "hi");

Error = No overload for method Box' takes 1’ arguments

Used google, no fix. I’ve used GUI.Box plenty of times before, I don’t know why it’s derping on this project.

I closed my console and refreshed my Scripts Folder, then re-opponened console and it was fine. Thanks for the help
