Comment navigation on main index

I want comments to be visible on the main index page, so I included the following code:

<?php $withcomments = true; comments_template();?>

This works great. However, the comment navigation links (‘next_comment_link’ and ‘previous_comment_link’) only appear on the my single.php template and not on the main index page.

Anybody have any ideas??

Many thanks to anyone who takes the time to read this…
