Scala播放传递变量以查看无法正常工作

在控制器中：

Ok(views.html.payment(message,test,x_card_num,x_exp_date,exp_year,exp_month,x_card_code,x_first_name,x_last_name,x_address,x_city,x_state,x_zip,save_account,product_array,x_amount,products_json,auth_net_customer_profile_id,auth_net_payment_profile_id,customer_id))

在视图中：

@(message: String,test: String,x_card_num: String,x_exp_date: String,exp_year: String,exp_month: String,x_card_code: String,x_first_name: String,x_last_name: String,x_address: String,x_city: String,x_state: String,x_zip: String,save_account: String,product_array: Map[String,Map[String,Any]],x_amount: String,products_json: String,auth_net_customer_profile_id: String,auth_net_payment_profile_id: String,customer_id: String)

但是,当我尝试向控制器添加一个变量并像这样查看时：

Ok(views.html.payment(message,customer_id,saved_payments_xml))


@(message: String,customer_id: String,saved_payments_xml: String)

它给了我这个错误：

missing parameter type

我究竟做错了什么？
