this.attachMovie(“nt_mc”, ‘graphic’, 1);
clipX = this._x;
clipY = this._y;
}
onClipEvent (mouseDown) {
if (this, hitTest(_root._xmouse, _root._ymouse)) {
this.attachMovie(“nts_mc”, ‘graphic’, 1);
this.startDrag();
this.dragging = true;
}
}
onClipEvent (mouseUp) {
stopDrag();
if (eval(_root.empty_mc._droptarget) != _root.et_ncf) {

Are you sure that the test returns true?

if (eval(_root.empty_mc._droptarget) != _root.et_ncf) {
  trace ("hit!");
  this.removeMovieClip();
}
