我无法访问我在laravel 4中从控制器发布的变量

i have laravel application. i posted variable $res in my controller to my view and in the view i have no access to the variable i posted. here is my code:

my route:

Route::get('/pickUpQuestion','createQuizController@showResult');

my controller:

public function showResult()
{
    $prio = Input::get('quiz_prio');

    $cat = Input::get('quiz_cat');

    $les = Input::get('quiz_less');

    $rdate = Input::get('date_start');

    $res = DB::select("select title from quiz where categories_id='$r2' and lesson_id='$r3' and priority_id='$r1' and date_start='$rdate'");

    return View::make('pickUpQuestion')->with('result',$res);
}

and my view:

@extends('layouts.master')

@section('content')

<?php
   var_dump($res);
?>
@stop

i take the values in my query from another form in a different view with post method to this view
