I guess my question wasn't very clear. Sorry. I used the code above. Works great. Now the user needs to be able to clear all copies. Below where the question marks are is where I am not clear. I tried removeChild, deleteSelection, deleteObject, etc. (note: this is used on a interactive whiteboard lesson)
MovieClip(root).lesson_mc.toolbar_mc.reset_mc.addEventListener(MouseEvent.MOUSE_UP, clearCopies);
function clearCopies(Event:MouseEvent):void {
?????????????????????????
}
