And i cant figure it out.

the “my.fla.class”

content looks like this

```auto
package my_fla
{
    import flash.display.*;
    dynamic public class myklassik extends MovieClip
    {
        public var randomStartingFrame:int;

        public function myklassik()
        {
            addFrameScript(0, frame1);
            return;
        }// end function

        function frame1()
        {
            randomStartingFrame = Math.round(Math.random() * 4--) + 1;
            gotoAndStop(randomStartingFrame);
            return;
        }// end function

    }
}

```

Thanx
