Members only can view sidebox

[misty]

Have tried to follow this archived thread at
http://www.zen-cart.com/forum/showth...debox+override
Got this far

<?php
$show_mp3player = false;
if ($_SESSION['customer_id'] != '') {
$show_mp3player = true;
} else {
if (STORE_STATUS == '0')
$show_mp3player= false;
}
  require($template->get_template_dir('tpl_temps.php',DIR_WS_TEMPLATE, $current_page_base,'sideboxes'). '/tpl_mp3_player.php');

  $title =  BOX_HEADING_MP3PLAYER;
  $left_corner = false;
  $right_corner = false;
  $right_arrow = false;
  $title_link = false;

  require($template->get_template_dir($column_box_default, DIR_WS_TEMPLATE, $current_page_base,'common') . '/' . $column_box_default);
?>

Sidebox I only want logged in members to view is still visible..any help or
advice gratefully received.. TIA
