I get the error: Script "menu editting" line 63: NameError occurred.
Undefined local variable or method 'start_actor_selection' for #<Scene_MenuOption:0x17c3718>

Hi.
Like the error says. You use the method "start_actor_selection" but you don't defined this method.
I think you copied some party from the "Scene_Menu" so I would copy the missing method also.

Code: [Select]

    @status_window = Window_MenuStatus.new(160, 0) # LOOK HERE  how do i know what numbers Come after it?

Do you mean (160,0) ?
Just look at the class you want to call and you'll find out.
Look at "initialize" and after this method are the needed parameter. In this case the x and y coordinate.

Like Deity said, it was because your start_actor_selection was undefined. This is because your start_actor_selection was below your update_command_action. Or at least I think it's like that. Anyways, try this script.

    end

end

Also, your start_actor_selection didn't have an end. When you define things, you should always put an end at the end of your code. Hope this helps!
