Error 1119 When Trying to Load Movie Clips

[coffeebeans]

Kind of a newbie, so bear with me, please. I'm setting up a minisite and have a navigation menu (functioning as a movie clip) that's meant to launch other movie clips. Code on the parent file:

var myLoader:Loader = new Loader();
myLoader.load(new URLRequest("main.swf"));
addChild(myLoader);

Code on the child movie clip:

stop();

function buttonClick(event:MouseEvent):void
{
    gotoAndStop(event.target.name);
    
    tyes.enabled = true;
    winterpassing.enabled = true;
    otherwork.enabled = true;
    author.enabled = true;
    
    event.target.enabled = true;
    this.parent.myLoader.load(new URLRequest(event.target.name + ".swf"));
}

tyes.addEventListener(MouseEvent.CLICK, buttonClick);
winterpassing.addEventListener(MouseEvent.CLICK, buttonClick);
otherwork.addEventListener(MouseEvent.CLICK, buttonClick);
author.addEventListener(MouseEvent.CLICK, buttonClick);

I've yanked this practically straight out of a book and have no idea why I keep getting this error message:

1119: Access of possibly undefined property myLoader through a reference with static type flash.display:DisplayObjectContainer.
this.parent.myLoader.load(new URLRequest(event.target.name + ".swf"));

Any ideas? Let me know if you need clarification...not sure I explained this too well.

This thread deals with a UILoader but I think you are having a similar issue.

Thank you! That did the trick. Changed one line from

this.parent.myLoader.load(new URLRequest(event.target.name + ".swf"));

to

(root as MovieClip).myLoader.load(new URLRequest(event.target.name + ".swf"));

Unfortunately, a new problem came up. Whenever I click on a button in the navigation, none of my other SWFs are showing up and I end up with this error message:

TypeError: Error #1009: Cannot access a property or method of a null object reference. at rapp_fla::mcMenu_1/buttonClick()

All of my SWFs are in the same directory as the parent SWF, are named correctly, and all work perfectly on their own, but just won't load within the main SWF.

trace this and see what you get

PHP Code:

trace(event.target.name + ".swf");

Ack, sorry, haven't been working in Flash for too long (as if that weren't obvious already). Where am I supposed to add or replace the trace line? I've tried a few different spots and haven't been able to figure it out.

function buttonClick(event:MouseEvent):void
{
    gotoAndStop(event.target.name);
    
    tyes.enabled = true;
    winterpassing.enabled = true;
    otherwork.enabled = true;
    author.enabled = true;
    
    event.target.enabled = true;
trace(event.target.name + ".swf");
    (root as MovieClip).myLoader.load(new URLRequest(event.target.name + ".swf"));
}

Did you ever get this fixed? I am having the same problem. I think we used the same book. Any help?
