Php 致命错误：调用成员函数couponNC（）

我用的是opencart

当我点击链接确认新成员时，我发现了一些问题

这是消息错误

致命错误：调用成员函数couponNC（）…第23行

第23行我的代码是

$this->generate->couponNC（$customer\u id）

couponNC是文件夹系统/库中的myfunction

我的文件generate.php和我的函数是

    <?php 
     private $db;

    public function __construct($registry)
    {
        $this->db = $registry->get('db');
        $this->config = $registry->get('config');
    }

    public function couponNC ($customer_id) {
    // my function code
    }

    ?>

帮我修一下。

这是我生成的.php@kyleDomingo
