Dispalying Posts in Specific Categories Tied to Current USer

Hi–I have been battling over the following script for a few days. My users are bound to categories (using wp_named_users plugin, which gives me a wp_named_users table in the Mysql database).
I have tried using the code below to select and display the posts of the specific categories relevant to the currently loggied inuser, which would display on his or her own ‘home page’. i have got the user home page set up, but cannot get this script to return values. Inner Join is posts.ID and named_users.post.id.

Please can I have any suggestions for why this script may not be returning a positive result–it goes into the “else” option all the time.

Thanks very much!!

<?php
$querystr = “
SELECT wpposts.*
FROM $wpdb->posts wpposts, $wpdb->named_users wp_named_users
WHERE wpposts.ID = wp_named_users.post_id
AND wp_named_users.user_id = ‘$current_user->ID’
AND wpposts.post_type = ‘post’
AND wpposts.post_status = ‘publish’
AND wpposts.post_date < NOW()
ORDER BY wpposts.post_date DESC
“;

$pageposts = $wpdb->get_results($querystr);

?>
<?php if ($pageposts): ?>
<?php foreach ($pageposts as $post): ?>
<?php setup_postdata($post); ?>

<div class=”post” id=”post-<?php the_ID(); ?>”>

<?php the_title(); ?></h2>
