I have this script which SHOULD produce a linked webpage for soon-to-be
created static web pages, however I can't seem to find the error in my
code:

<?php
//connect to database
include 'db.php';

$display_block = "<h1>PFS Sales Categories</h1> <P>Select a category to
see its items.</p>";

//Show categories first
$get_cats = "select id_num, id_name, description, cat_code from
PFS_categories order by id_name"; $get_cats_res = mysql_query($get_cats)
or die(mysql_error());

if (mysql_num_rows($get_cats_res) < 1)
{
 $display_block = "<P><em>Sorry, no categories to browse.</em></P>"; }
else {  while ($cats = mysql_fetch_array($get_cats_res))  {
  $cat_id = $cats[id_num];
  if ($cat_id != "53" || $cat_id != "54" || $cat_id != "55" || $cat_id
!= "117" || $cat_id != "118")
  {
  $cat_title = strtoupper(stripslashes($cats[id_name]));
  $cat_desc = stripslashes($cats[description]);
  $display_block .= "<strong><a
href=$_SERVER[PHP_SELF]?cat_id=$cat_id>$cat_title
$cat_desc</a></strong><br>\n";

  if ($_GET[cat_id] == $cat_id) //get items
  {
   $get_items = "select id, item_num, description from PFS_items where
cat_code = $cat_id";
   $get_items_res = mysql_query($get_items) or die(mysql_error());

   if (mysql_num_rows($get_items_res) < 1)
   {
    $display_block = "<P><em>Sorry, no Items to browse.</em></P>\n";
   }
  else
  {
#   $display_block .= "<ul>\n";
   while ($items = mysql_fetch_array($get_items_res))
   {
    $item_id = $items[id];
    $item_num = $items[item_num];
    $item_desc = stripslashes($items[description]);
    if ($item_num != "ABC-R37" || $item_num !=  "ABC-R42" || $item_num
!= "HB-99100" || $item_num != "RO-PUMPS" || $item_num != "ML-HDGALJUG"
|| $item_num != "PFS-CAC21" || $item_num != "PFS-CO2")
    {
    $display_block .= "&nbsp;&nbsp;&nbsp;&nbsp;<em><strong><a
href=\"catalog/$item_id.html\">$item_num</strong> -
$item_desc</em><br>\n";
    } 
   }
#   $display_block .= "<br>\n";
#   $display_block .= "</ul>\n";
  }}
 }
}
