Need help with a 1119 error plz

programming flash
1

Description
1119:Access of possibly undefined property myLoader through a reference with static type flash.display.DisplayObjectContainer.

Source
this.parent.myLoader.load(new URLRequest(event.target.name + “.swf”));

I am pretty new to CS3 and i cant understand why i am getting this compiler error. The source is in a mc with buttons of the same name as the external swfs it loads. This mc is in my main Timeline. I cant get my main Timeline(menu) to load any external swf. :frowning:

I would really appreciate some advice on this problem if anyone can.
Thanks in advance.
