help...this produces a blank page, even though i've made the templates...

PHP Code:

<?
chdir("../forums");
require("global.php");
$cats = $DB_site->query("SELECT * FROM classified_cat WHERE parent = '0' ORDER BY displayorder, title");
while ($cat = $DB_site->fetch_array($cats)) {
 eval("\$catbit .= \"".gettemplate("classifieds_indexbit_level1")."\";");
 $subcats = $DB_site->query("SELECT * FROM classified_cat WHERE parent = '".$cat[id]."' ORDER BY displayorder, name");
 while ($subcat = $DB_site->fetch_array($subcats)) {
  eval("\$catbit .= \"".gettemplate("classifieds_indexbit_level2")."\";");
 }
}
echo $catbit;
eval("dooutput(\"".gettemplate("classifieds_index")."\");");
?>
