Routing issue causing Symfony \ Component \ HttpKernel \ Exception \ NotFoundHttpException error

I am getting this error when testing my code. I know it is a routing issue but I can't see anything wrong with my routes.

Here is the routes that are causing the problems:

Route::get('/messages', 'MessageController@create');
Route::get('/messages/show/{comment}', 'MessageController@show');

Here is the controller:

class MessageController extends BaseController
{

protected $messageForm;

public function __construct(MessageForm $messageForm, MessageRepository $messageRepository,
  MessageRecord $messageRecord)
{
    $this->messageForm = $messageForm;
    $this->messageRepository = $messageRepository;
    $this->messageRecord = $messageRecord;
}

/**
 * Display a listing of the resource.
 * GET /messages
 *
 * @return Response
 */
public function create()
{
    return View::make('message.create');
}



public function show($comment)
{
    $message_id = $this->messageRepository->find($comment);
    return View::make('message.show')->with('comment', $message_id);
}

/**
 * Store a newly created resource in storage.
 * POST /messaages
 *
 * @return Response
 */
public function store()
{
    $data = Input::all() ;
    $this->messageForm->validate($data);

    $messageRecord = new MessageRecord;
    $messageRecord->comment = $data['comment'];

    Return "Comment created";
}
}
