Topic: Scriptaculous and drag and drop - how to remove the old draggable?

Using Scriptaculous, I need to remove the old Draggable and Droppable
once a drag and drop is complete.  If I don't IE doesn't work for the second drag and drop.

So the drag and drop calls an RJS in which I have tried 3 ways to remove
this.
1___________________________________________________________

page.remove("second_appt_drag_div"+@appt_id)
page.remove('second_appt_drop_div'+@drop_time)

This gives an RJS error -
TypeError: element has no properties
It shows as Element.remove("second_appt_drag_div172");
Element.remove("second_appt_drop_div20070712");
on the Ajax error.

But it does remove the Draggable - (but not the Droppable)
2___________________________________________________________

page.call << Droppables.remove('second_appt_drop_div'+@drop_time);
page.call << Draggables.unregister('second_appt_drag_div'+@appt_id);

or

page.call << "Droppables.remove('second_appt_drop_div'"+@drop_time
+");"
page.call << "Draggables.unregister('second_appt_drag_div'"+@appt_id
+");"

Gives a Rails error

ActionView::TemplateError (wrong number of arguments (0 for 1))
3__________________________________________________________
In the RJS
page.DragndropClearup('div#second_appt_drag_div'+@appt_id,
'div#second_appt_drop_div'+@drop_time)

and then in the application.js

function DragndropClearup(AppId, DropTime){
        Droppables.remove(DropTime)
        Draggables.unregister(AppId);

}

No errors - but does nothing!

This should be easy to do - but I can't find the way!  Any ideas?
