VX ACS crafting system variable attachment

So im working on this game with my cousins, were using the crafting system ACS, and wish to remove it from the menu until later in the game. we have tried attaching a variable to the switch and having an event activate the switch, but the script isn't set up to be attached to a variable and we get the error 

'Script 'Redefinitions' Line 27: NoMethodError Occurred.
undefined method '[]=' nil:NilClass

thats the error the coding i have for the switch is this

 #--------------------------------------------------------------------------
    # Set this to true if you want to disable the "crafting" entry in the menu
    #--------------------------------------------------------------------------
    @disableMenuChoice[0015] = true
   
    super
    create_menu_background
    if @disableMenuChoice
      oldCmdWindow
    else
      create_command_window
    end
    @gold_window = Window_Gold.new(0, 360)
    @status_window = Window_MenuStatus.new(160, 0)
  end


the varriable is an old man so we can have him teach you to craft

first it sets move rout to face you, he asks you if u want to learn to craft, if you choose yes it turns control switch 0015 on, if no it turns it off, i cant copy the text so i hope this helps, the 3 of us together cannot figure this out. i read that the author was going to fix a similar issue in the next version, but cant find any newer than 2.21 please help

I think Pacman made a menu script that you can add/remove menu options. If you don't want the classic feel you can use one of MA's menu scripts

Replace that with this

Code: [Select]

    @disableMenuChoice = $game_switches ? $game_switches[15] : true
   
    super
    create_menu_background
    if @disableMenuChoice
      oldCmdWindow
    else
      create_command_window
    end
    @gold_window = Window_Gold.new(0, 360)
    @status_window = Window_MenuStatus.new(160, 0)
  end

When the switch is on, it will function normally.
@X - I haven't implemented that feature exactly yet. I'm working on it.
