Comment Form not showing

Just published a new blog posting and my comment form has disappeared.

I have checked the Discussion settings and the setting to allow people to post a comment on new articles is checked. Comment author must fill out name and email is also checked.

The “allow comments” button on the post in question is also checked.
I am running 3.1.3 with the 2010 Theme. I am not overly confident with editing, but I think my comments.php file may be the problem.
Here is part of the file concerning comments:

<div id="comments">
<?php if ( post_password_required() ) : ?>
<p class="nopassword"><?php _e( 'This post is password protected. Enter the password to view any comments.', 'twentyten' ); ?></p>
			</div><!-- #comments -->

I am a newbie and would like to know if I am on the right track and if there is anyone out there that can tell me how to fix it, and what code should be there in it’s place.

Thanks,
VBA1
