Plugin Woes

Help , i cannot seem to get Alex’s WP since last visit to work…
i am unsure of this part of the readme onwards.
Step 4.
Add some code to show the number of new posts and comments since your last visit
<script type=”text/javascript”>slvBanner();</script>
Step 5.
Add some code to show the new indicator next to each post (index.php)
<script type=”text/javascript”>slvShowNewIndicator(<?php print(mysql2timestamp($post->post_date)); ?>);</script>
Step 6.
Add some code to show the new indicator next to each comment (wp-comments.php and wp-comments-popup.php)
<script type=”text/javascript”>slvShowNewIndicator(<?php print(mysql2timestamp($comment->comment_date)); ?>);</script>
Step 7.
To show if there are new comments on a post from the link to the comments for that post, replace the comments_popup_link() in the posts loop with ak_comments_popup_link()
Step 8.
Put the ‘ak-img’ directory in your blog root, you can set the indicator you want (or use a text indicator) by modifying this code in wp-last-visit.php
// var slvIndicator = ‘New’;
var slvIndicator = ‘<img src=”<?php echo $siteurl ?>/ak-img/new.gif” alt=”New” title=”New since your last visit.” />’;
remove the “//” from the first line and put it on the second line to use the text indicator.
any ideas?
