incorrect region variables for left & right sidebars in page.tpl.php

In the Drupal 6 version of this theme, the sidebar variables are not correct in page.tpl.php. It reads:

<div id="sidebar">
	<?php if ($search_box): ?>
		<?php print $search_box ?>
	<?php endif; ?>
	<?php print $sidebar_left ?>
	<?php print $sidebar_right ?>
</div>

It should read,

<div id="sidebar">
	<?php if ($search_box): ?>
		<?php print $search_box ?>
	<?php endif; ?>
	<?php print $left ?>
	<?php print $right ?>
</div>
