I'm not sure what you're trying to do, but the mistake is probably 
related to this line:

	menu_shipment = FXMenuCascade.new(menu_operation, "Shipment")

If your intention was to have the "Add" menu command be one of the 
commands in the "Shipment" sub-menu, you need to first create a menu 
pane to hold the "Add" command:

	shipment_menu_pane = FXMenuPane.new(self)

and add some commands to it:

	FXMenuCommand.new(shipment_menu_pane, "Add Shipment")
	FXMenuCommand.new(shipment_menu_pane, "Remove Shipment")
	FXMenuCommand.new(shipment_menu_pane, "Check Shipment Status")

and finally add the "Shipment" sub-menu to the parent menu pane 
(menu_operation), specifying that the "Shipment" menu cascade item is 
supposed to pop-up the shipment_menu_pane:

	FXMenuCascade.new(menu_operation, "Shipment", nil, shipment_menu_pane)

So in this scenario, you've got an "Operation" pulldown menu on the 
menu bar. One of the items inside that menu is labelled "Shipment", and 
it's a cascading menu. When you pick "Shipment", it pops up a sub-menu 
with the "Add", "Remove", and "Blah" options.

For examples of how to use FXMenuCascade, see the groupbox.rb example 
included with FXRuby.

Hope this helps,
