Custom Fields Help

I am using a custom field “rdate” to enter the current date or date of event for my post. I am trying to query this information on my sidebar, but can’t get it to work. Can someone please help me with this code, so that it will so my information.

<?php
global $query_string;
query_posts( $query_string . ‘&meta_key=rdate&orderby=meta_value&order=asc’);?>
<?php while (have_posts()) : the_post(); ?>

<?php the_title(); ?>

<?php endwhile;
wp_reset_query();?>

I was using the plug-in “Advanced Custom Fields” and this query worked. I changed to “Types – Complete Solution for Custom Fields and Types” because my post category check boxes wouldn’t work with Advanced Custom Fields. Now, my query doesn’t work. Does anyone know how I can fix this?
