Show link outside post not inside…

Hey!
I’m using a plugin that autopost to IP.Board.
This plugin shows a link to the post in IP.Board when I click on read more.. But I want that link outside the post!
How can I do that?

I have this code but it isn’t working:

<?php $meta = get_post_meta($post_ID,'forum_topic_url');
if ( ! empty($meta) ) : $topic_link = current($meta); ?>
<a href="<?php echo $topic_link; ?>">Follow the Discussion in Progress</a>
<?php endif; ?>

Here is the plugin-code:
