1120: Access of undefined property mySnd.

I have simplified the code to post here, the issue is I keep getting the 1120 error, yesterday it worked like it should, today it throws the error. I just don’t get it, it has happened more then once.

```auto

package {
    
    import flash.media.*;
    import flash.events.*;
    

    public class MyClassXYZ extends MovieClip {

        var mySnd:Sound = new Sound();
             mySnd.load(new URLRequest("xyz.mp3"));
             mySnd.addEventListener(Event.COMPLETE, mySndLoader, false, 0, true);
        function mySndLoader(e:Event):void {mySnd.play();}
    }
}

```

Any suggestions or info would be appreciated, I am sure I will figure it out, next time I open Flash.

Thanks
