Problem with adding a new post type

Question

I want to add a new post type

i have a php file (posttype.php) at : wordpress/wp-content/themes/

this is the code :

<?php
// Add new post type for Recipes
add_action('init', 'cooking_recipes_init');
function cooking_recipes_init() 
{
    $args = array(
        'label' => _x('Recipes'),
        'singular_label' => _x('Recipe'),
        'public' => true,
        'publicly_queryable' => true,
        'show_ui' => true, 
        'query_var' => true,
        'rewrite' => true,
        'capability_type' => 'post',
        'hierarchical' => false,
        'menu_position' => null,
        'supports' => array('title','editor','comments')
    ); 
    register_post_type('recipes',$args);
}
?>

i have a problem at the top of the page (but the posttype is created suc) :

Warning: Missing argument 2 for _x(), called in D:\xampp\htdocs\wordpress\wp-content\themes\posttypes.php on line 12 and defined in D:\xampp\htdocs\wordpress\wp-includes\l10n.php on line 189

Thank you .

_x() requires a context, either remove it completely or set it to something like 'Recipe Singular' and 'Recipe Plural'.
