グローバル 'addButtons'（ゼロ値）を呼び出そうとしました

Question

私はGMODゲームモードで本当に面倒なエラーが発生しました。私は、カスタムメニューを作成しようとしていますが、私はこのエラーを取得する：ここで

[ERROR] gamemodes/tdm/gamemode/custom_menu.lua:20: attempt to call global 'addButtons' (a nil value) 
    1. gameMenu - gamemodes/tdm/gamemode/custom_menu.lua:20 
    2. unknown - gamemodes/tdm/gamemode/custom_menu.lua:32 
    3. include - [C]:-1 
    4. unknown - gamemodes/tdm/gamemode/cl_init.lua:3 

は私のコードです：

あなたは関数定義はconcommand.Add("open_game_menu", gameMenu())後、以下のように、この時点でnilあるaddButtons(Menu)を呼び出し

concommand.Add("open_game_menu", gameMenu()) 

を呼び出します。

すべてです。エラーメッセージを読むだけでいいです。
