Greetings,
I have a little program that creates a menu, however, it's not setting the
global varible race_bonus when you activate the menu item like it should.
Can anyone explain to me why it does not seem to be doing this ? I know how
to do it the long way, but I'd perfer to do it this way (using the
add_to_menu() function) if possible. Thanks.
Sincerely,
Randy
