Comments to show on index

I have no. of posts set to 1, so I have 1 post showing on the index page. How do I make it so that the comments for that post show on the index page too?

Noticed that putting in the the template tags
<?php comments_popup_link(__(‘Comments (0)’), __(‘Comments (1)’), __(‘Comments (%)’)); ?>
and
<?php comments_popup_script(400, 500); ?><?php comments_popup_link(‘No comments yet’, ‘1 comment so far’, ‘% comments so far (is that a lot?)’, ‘comments-link’, ‘Comments are off for this post’); ?>
in index.php only shows up while in index and not in individual posting. The tags are put in after the post loop, not in the comment loop. Would’ve thought that individual posts would be the same as index.php (I’m using a template without singles.php) and vice versa.
