Deleting movie clip

1

I have this mc that i would like to be deleted but the removeMovieClip function dosent seem to work on it.

I have this in the frame

// Location
loc=0;
function placeLoc() {
      if(loc==0){
    duplicateMovieClip(_root.location_mc,"location_mc",1);
  _root.location_mc._x = _root.info_mc._x-10;
   _root.location_mc._y = _root.info_mc._y+65;
   loc=1
       trace(loc)
}else if(loc==1){
    loc=0
//clip to be deleted here
    trace(loc)
}
}

and this in the button that displays the clip

on(press) {
    _root.placeLoc();
    }
