Actionscript 3 coding to return to home page 10 secs after sound file stops

Thank you Ned for your help, however as I do not really understand how the settimeout function works, it has now made me more confused.

I think I have nutted out what I am trying to say.

Essentially my project is like a web page if you like.

I have six individual pages which all display a picture and play a sound file.

What I would like to do is after each page is selected it will play a sound file, I then want it to wait 10 secs and then go back to a

home page (which will be frame 1) or if they are impatient there is a back button that directs you back to frame 1.

I have included the code used by the back button to manually get back to frame 1 either whilst the sound file is playing or after it has finished

back_btn.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToGoToAndStopAtFrame_1);

  function fl_ClickToGoToAndStopAtFrame_1(event:MouseEvent):void

{

    gotoAndStop(1);

}

/* Click to Stop All Sounds

Clicking on the symbol instance stops all sounds currently playing.

*/

back_btn.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToStopAllSounds);

function fl_ClickToStopAllSounds(event:MouseEvent):void

{

    SoundMixer.stopAll();

}

I just want it to return to home page automatically once the sound file is finished and there is nil input from the touch screen. (This will simulate someone walking away midway and leaving it with 2nd  web page showing.)

I hope this makes sense.

Thank you
