AS3 to AS3 Drag/Drop Question

Question

This is a fairly routine drag/drop interaction. The tricky part is when the invisilbe button 'btnInvis10' is clicked, another movieClip, 'dragger' appears and becomes the element being dragged, to be dropped onto 'mSquare'.  AS3 is giving me some problems when I convert the code - really just changing the functions to be AS3 compliant. But I guess it needs more than just converting. Any ideas?
My AS2 code worked like this:
dragger._alpha = 0;
btnInvis10.onPress = function():Void  {
dragger._alpha = 100;
dragger.startDrag(true);
onMouseUp = function ():Void {
var bOverlap:Boolean = dragger.hitTest(mSquare);
//trace(bOverlap);
if (bOverlap) {
  dragger._alpha = 0;
  btnInvis10._visible = false;
  menubar._x = _xmouse;
  menubar._y = _ymouse;
  gotoAndStop(nextFrame());
  bOverlap = false;
if (!bOverlap) {
  dragger._alpha = 0;
  dragger._x = 412;
  dragger._y = 490;
dragger.stopDrag();

Can you show your AS3 attempt as well?
I figure I should ask if the coding is errant wrt the way you test if bOverlap is true vs false (since it may be as intended).  In the first conditional where it is true, it is set to false, which will cause the condition that follows it to also run since it is now false...
if (bOverlap) {
  bOverlap = false;
if (!bOverlap) {
One last thing... gotoAndStop(nextFrame());  doesn't make sense (to me).  nextFrame does not return a value, so using it as an argument doesn't buy anything.  By itself it will cause the timeline to move to the next frame and stop.
