wp_list_bookmarks

Hi,

I am trying to insert a bookmark id into the ‘before’ part of each bookmark. My code is as follows:

<?php $bookmarksArgs = array(
    'orderby'          => 'rating',
    'order'            => 'ASC',
    'category_name'    => 'Main Nav',
    'hide_invisible'   => 1,
    'show_updated'     => 0,
    'echo'             => 1,
    'categorize'       => 0,
	'title_li'		   => '',
    'class'            => 'linkcat',
    'before'  => '<li id=\"%id\">',
    'after'   => '</li>' ); ?>
	<?php wp_list_bookmarks( $bookmarksArgs ); ?>

But the output just includes <li id=\”%id\”> and not <li id=”[bookmark id]”>.

Why is this? I’m new to wordpress and really keen to get going! Can’t wait to get my blog live once I’ve got the templates sorted out!
