count_twittersが未定義というエラー

Question

Undefined variable: count_twitters (View: /home/ec2-user/environment/twitter-clone/resources/views/users/show.blade.php)
上記のエラーが出たのですが、自分では原因が見つけれていないので質問させて頂きます。
Twitterのクローンサイトを作りたくて、まずは教科書から真似てコードを書いています。

お手数おかけしますが、ご教示お願いします。

Answer 1

    public function followings($id)
    {
        $user = User::find($id);

        return view('users.show', [
            'user' => $user,
        ]);
    }

ここでもshow.blade.php使ってそうですが、あってますか？
