CS3 Error #1009 when trying to use swf address in a document class

1

I’m trying to have a document class using SWFAddress & gSkinners framescript manager class but keep getting SWFAddress errors…
This is the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.asual.swfaddress::SWFAddress$/::_getValue()
at com.asual.swfaddress::SWFAddress$/::_check()
at flash.utils::Timer/flash.utils:Timer::_timerDispatch()
at flash.utils::Timer/flash.utils:Timer::tick()

This is the documentclass code:

  package {

import flash.events.*;
import com.gskinner.utils.FrameScriptManager;
import flash.display.*;
import com.asual.swfaddress.*;  
import caurina.transitions.*;
import caurina.transitions.properties.*;
    
public class Website extends MovieClip {
        
// constructor:
    public function Website() {
        
        //FrameScript setup
        super();
        SWFAddress.addEventListener(SWFAddressEvent.CHANGE  , handleSWFAddress);
        var fsm:FrameScriptManager = new 
                    FrameScriptManager(this);
        fsm.setFrameScript("$/",homeFunct);
        fsm.setFrameScript("$/about/",aboutFunct);
        fsm.setFrameScript("$/portfolio/",portfolioFunct);            
                    fsm.setFrameScript("$/contact/",contactFunct);
        
        
        
    }

public function replace(str, find, replace):String {
return str.split(find).join(replace);
}

    public function toTitleCase(str):String {  
    return str.substr(0,1).toUpperCase() + str.substr(1).toLowerCase();  
    }  
 
    public function formatTitle(addr):String {  
    if (addr.substr(addr.length - 1, 1) == '/') {  
    addr = addr.substr(0, addr.length - 1);  
    }  
    return 'Webbmall' + ((addr.length > 0) ? ' / ' + toTitleCase(replace(addr.substr(1), '/', ' / ')) : '');  
    }
    
    // SWFAddress handling  
    public function btnClick(event:MouseEvent):void {  
    SWFAddress.setValue(event.target.link);  
    }  
     
    public function btnRollOver(event:MouseEvent):void {  
    SWFAddress.setStatus(event.target.link);  
    }  
     
    public function btnRollOut(event:MouseEvent):void {  
    SWFAddress.resetStatus();  
    }
    
    public function handleSWFAddress(event:SWFAddressEvent):void {  
    if (currentFrame == 2 && event.value == '') {  
    play();  
    } else {  
    gotoAndStop('$' + event.value);  
    if (currentLabel == null) {  
    gotoAndStop('$/error/');  
    }  
    }  
    SWFAddress.setTitle(formatTitle(event.value));  
    }  

// private methods, webbsidans olika sektioner:

//***************************************

    private function homeFunct():void {

// trace(“hem”);
stop();

}

//**************************************

//**************************************

    private function aboutFunct():void {

// trace(“om oss”);
//
}

//***************************************
// Portfolio

//
}

//*********************************************
// Kontakt - contact
//*********************************************
private function contactFunct():void {
//trace(“kontakt”);

    }
    
    
}

}
I would really appreciate some help with this one.
I’ve read that it’s usually an issue of stage or root access but I’m not sure - still new to AS3.
I also have some preload code on frame 1 in the movie:

function enterFrame(e:Event){
var bl:int = loaderInfo.bytesLoaded;
var bt:int = loaderInfo.bytesTotal;
if (bl && bt && bl == bt) {
removeEventListener(Event.ENTER_FRAME, enterFrame);
nextFrame();
} else if (loading_mc.bar_mc) {
loading_mc.bar_mc.scaleX = bl/bt;
}
}
addEventListener(Event.ENTER_FRAME, enterFrame);
stop();
All the best, Niklas
