Loading An Edge composition at a certain frame

What I would like to do is to load  my Edge composition at a certain frame.

I would like to tell the Edge composition where to stop at, within my html file.

This because I need to load the comp at a different position in the timeline, depending on the html page where I need to place it.

I was able to start playing the comp

<script type="application/javascript">

  var comp;

  AdobeEdge.bootstrapCallback(function(compId) {

  // "comp" is now equivalent to the Stage's "sym" variable.

  comp = AdobeEdge.getComposition(compId).getStage();

  comp.play();

  });

</script>

but I would actually want to tell the comp to play at a label.. something like

comp.play("label");

but thats not working...

I am not very familiar with js since I come from After Effects, so it would be nice if someone could provide an example or point another discussion where this problem was solved.

Thanks
