I'm trying to incorporate a Gwolle Guestbook into my category template by having it pull guestbook entries from another page. So I use the PHP code
<?php show_gwolle_gb(129); ?> into my template and I've tried that with both an ID and no ID. Either way, I get the following message:
Fatal error: Call to undefined function show_gwolle_gb() in /home/content/html/wordpress/wp-content/themes/twentyeleven/category-1.php on line 92
Any idea how to correct this? The whole idea is to have a list of posts on one side and the guestbook posts and form on the other.
