Thanks for the response. Here’s the code:

<div id=”sidebar”>

<h2>Get the A.I. Newsletter!</h2>
<?php
$content = apply_filters(‘the_content’, ‘<!–phplist form–>’);
echo $content;?>

<?php /* Widgetized sidebar, if you have the plugin installed. */
if ( !function_exists(‘dynamic_sidebar’) || !dynamic_sidebar(right) ) : ?>
<li id=”search”>
<?php include (TEMPLATEPATH . ‘/searchform.php’); ?>

<?php if ( is_404() || is_category() || is_day() || is_month() ||
is_year() || is_search() || is_paged() ) {
?>

• <?php /* If this is a 404 page */ if (is_404()) { ?>
