[Plugin: Rotating Posts] I’m having trouble getting this started.

I read the instructions in the readme and couldn’t find the “settings” for this that you mentioned also, I updated my index.php to include the rotating posts. see below. Please let me know what I’m doing wrong because nothing is rotating. thanks

* @subpackage constructor
*/
// Stupid Parser This is Theme support the Gravatar Service
// get_avatar();

// load header.php
get_header();

// load one of layout pages (layout-*.php)
get_constructor_layout(‘index’);

<div id=”content” class=”narrowcolumn”>

<?php rotating_posts(); ?>

</div>

// load footer.php
get_footer();
?>
