How to use a symbol instance on the stage in an external package?

Hi All,

I am new to ActionScript and Flash. I am trying to develop a simple screen with a few symbols (button) and a youtube player(this part has already been taken care of- thanks to Ben Longoria's great class object).

I have a symbol called s1 in the library and I also created an instance of it on the stage on the first frame, its name is myS01

Before I linked the document to a class (this was for youtube player) I was able to add event listeners, such as mousevents, onto this instance in my actions panel. But, after I linked my document to the external class in a package without a name, I cannot add any code into Actions panel, because it gives me all kinds of weird problems.

Instead I am trying to use this symbol and add listeners to it in my external class file (the one linked to the document) with no luck.

my external class file looks like:

package {
    import flash.display.Sprite;
    import flash.display.Stage;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import src.com.enefekt.tubeloc.MovieSprite;
    import src.com.enefekt.tubeloc.event.*;
   
        import fl.controls.Button;
   
    /**
     * Example class for MovieSprite class and the chromed player
     * @7111211 Ben Longoria enefekt@gmail.com
     */
    [SWF(backgroundColor="#FFFFFF")]
    public class MainChromed extends Sprite {
        private var youtubeMovie:MovieSprite;

        public function MainChromed() {
                youtubeMovie = new MovieSprite("NN2I1pWXjXI");
                youtubeMovie.addEventListener(PlayerReadyEvent.PLAYER_READY, onPlayerReady);
                youtubeMovie.x = 250;
                    youtubeMovie.y = 160;
                addChild(youtubeMovie);
        }
       
        private function onPlayerReady(event_p:PlayerReadyEvent):void {
                    youtubeMovie.width = 320;
                    youtubeMovie.height = 240 + MovieSprite.CHROME_HEIGHT;
        }
    }
}

How would I use my myS01 instance of s1 in this .as file? I just want to be able to refer to it.

For example, I tried adding:

private var b:s1 = new s1(); right after the line private var youtubeMovie:MovieSprite;

,but got the following error:

1120: Access of undefined property b.

Any suggestions would be very helpful.

Thank you for your time in advance,
