Creating a window within a window GUI

Unity Engine
1

I did this exact same thing on the main menu screen but with an options button opening a new options gui.

I just want to create a new gui box and buttons after this button is clicked. I am getting now console errors, but no box is appearing. (I have assigned the appropriate textures.)

#pragma strict

//var startButton : Texture;
var numLives : GUIText;
var numIneternets : GUIText;

var pauseMenu = false;
var menuBox : Texture;
var quit : Texture;

var pauseButtonReturn : Texture;
var pauseButton : Texture;
var playButton : Texture;

var isPaused : boolean = true;


numLives.text = "Lives: " + ply.currentPlayerLives.ToString();
numIneternets.text = "Internets: " + ply.internets.ToString();

function menuAppear() {
		GUI.Box (Rect (Screen.width / 2 + 15, Screen.height / 2 - 100, 200, 200), menuBox,  "");
    	if (GUI.Button(Rect(Screen.width / 2 + 22, Screen.height / 2 - 91, 120, 120), quit, "")) {
    			Application.Quit();
    		
    		
    		
    	}
}

function OnGUI() {
	if (GUI.Button (Rect (Screen.width / 350, (Screen.height / 2) + 240, 50, 50), pauseButton, "")) {
	    	if (isPaused != true) {
	    		pauseMenu = false;
	        	Time.timeScale = 0.0;
	        	isPaused = true;
	        	audio.Pause();
				pauseButton = playButton;
	        	
	        	} else {
	        		pauseMenu = true;
	        		Time.timeScale = 1.0;
	        		isPaused = false;
	        		audio.Play();
	        		pauseButton = pauseButtonReturn;	       
	        		      
	       }
	       if (pauseMenu){
	       menuAppear();
	       
	       }
		}

}

What are the console errors?
