have UILoaded swf talk to parent

I have a main fla that will load many external swfs sequencially in a timeline, two frames for each. The main timeline will advance only one frame, play the newly loaded swf and wait. I want each swf to tell the parent when it is done playing, and advance the parent to the next frame where there will be a next button and a replay button. I figured that I need an event listener in the parent, but how do I write the code for the child? I plan to have all loaded swfs coming from an images folder, and that part works fine

tahnks in advance for any help

I'm not sure what version of actionscript you're using, but in AS2, you can refer to the main swf from a child swf using the scope _root

Like, inside your child swf, you use something like: root.nextFrame(); or something like that.

used this for the child:
stage.dispatchEvent(new Event("cComplete"));

and this in the parent:
stage.addEventListener("cComplete",slideCompleteHd lr);
function slideCompleteHdlr(e:Event):void{
this.nextFrame();
}
