Hi, so I’ve read through all the other forums trying to figure this out, getting error in output

TypeError: Error #1009: Cannot access a property or method of a null object reference.  
at testweb\_fla::MainTimeline/mouseDownHandler3()

swf loads main page, there are 4 buttons, they are linked to frame labels for content, it throws this error when I hit 3/4 buttons, the 4th button (menu) goes to the right frame and loads jpg menu image, when I hit any of the other three buttons after hitting the menu button they work perfectly, its only after i hit the 1 button that enables me to navigate to the other pages.

import flash.events.MouseEvent;  
import flash.net.URLLoader;  
import flash.net.URLRequest;  
import flash.display.Loader;  
import flash.display.SimpleButton;

stop();

cnut1.buttonMode = true;  
cnut1.addEventListener(MouseEvent.CLICK, onButtonClick1);

function onButtonClick1(e:MouseEvent):void  
{  
e.currentTarget.gotoAndPlay(“Click”);  
}

Home.addEventListener(MouseEvent.MOUSE\_DOWN, mouseDownHandler1);  
function mouseDownHandler1(event:MouseEvent):void  
{  
imageLoader1.unload();  
imageLoader2.unload();

```
gotoAndStop("Home");

```

}  
Media.addEventListener(MouseEvent.MOUSE\_DOWN, mouseDownHandler2);  
function mouseDownHandler2(event:MouseEvent):void  
{  
imageLoader1.unload();  
imageLoader2.unload();

```
gotoAndStop("Media");

```

}

Faq.addEventListener(MouseEvent.MOUSE\_DOWN, mouseDownHandler3);  
function mouseDownHandler3(event:MouseEvent):void  
{  
imageLoader1.unload();  
imageLoader2.unload();

```
gotoAndStop("FAQ");

```

}

Men.addEventListener(MouseEvent.MOUSE\_DOWN, mouseDownHandler4);  
function mouseDownHandler4(event:MouseEvent):void  
{

```
gotoAndStop("Menu");

```

}

and then on a different layer at frame 5-10 label “Menu”

var imageLoader1:Loader = new Loader();  
var image1:URLRequest = new URLRequest(“coconut1.jpg”)

imageLoader1.load(image1);  
addChild(imageLoader1);  
imageLoader1.x=425;  
imageLoader1.y=110;

var imageLoader2:Loader = new Loader();  
var image2:URLRequest = new URLRequest(“coconut2.jpg”)

var imageLoader3:Loader = new Loader();  
var image3:URLRequest = new URLRequest(“coconut3.jpg”)

btnM1.addEventListener(MouseEvent.CLICK, nextMenu);  
function nextMenu (MouseEvent):void  
{

```
imageLoader2.load(image2);
addChild(imageLoader2);
imageLoader2.x=425;
imageLoader2.y=110;

```

}

btnM2.addEventListener(MouseEvent.CLICK, nextMenu1)  
function nextMenu1(event:MouseEvent):void  
{

```
imageLoader3.load(image3);
addChild(imageLoader3);
imageLoader3.x=425;
imageLoader3.y=110;

```

}

any help would be most appreciated, thanks.
