Issue with Custom Taxonomy in WP Deals Plugin

Hi,

I am trying to add a custom Taxonomy to this plugin code so I can use it for changing my URL structure.

Below is the code I added to the WPDeals-Taxonomy.php file and it added a new Area for entering my values for a particular deal.

register_taxonomy( 'citydeals', 'post',
                   array(   'hierarchical' => FALSE, 'label' => __('citydeals'),
                        'public' => TRUE, 'show_ui' => TRUE,
                        'query_var' => 'rating',
                        'rewrite' => true ) );
add_filter('post_type_link', 'citydeals_permalink', 10, 3);

function citydeals_permalink($permalink, $post_id, $leavename) {
    if (strpos($permalink, '%citydeals%') === FALSE) return $permalink;

        // Get post
        $post = get_post($post_id);
        if (!$post) return $permalink;

        // Get taxonomy terms
        $terms = wp_get_object_terms($post->ID, 'citydeals');
        if (!is_wp_error($terms) && !empty($terms) && is_object($terms[0])) $taxonomy_slug = $terms[0]->slug;
        else $taxonomy_slug = 'deals';

    return str_replace('%citydeals%', $taxonomy_slug, $permalink);
}

My issue here is that the value that I enter in the field to enter values for this citydeals taxonomy is not getting picked up when I change my Permalink structure to /%citydeals%/%postname%/

Please help..This is a very important feature that I need to be working.
