problem with adding comments to single.php

hello again,
I want to list all of the comments for one post under it’s content
this is my code for single.php:

<!--item -->
            <?php if (have_posts()) : ?>
            <?php while (have_posts()) : the_post(); ?>
            <div class="item">
            	<div class="top">
                	<div class="icon">
                    </div>
                    <div class="title">
                    	<h1><?php the_title(); ?></h1>
                        <p class="meta"><?php the_time('j.m.Y') ?> | Category: <?php the_category(', '); ?></p>
                    </div>
                    <div class="clear">&nbsp;</div>
                 </div>
                 <div class="text">
                    	 <?php the_content(); ?>
                 </div>
                 <div class="bottom">
                 	<div class="postComments">
                    	<a href="<?php comments_link(); ?>"><?php comments_number('comment','1 comment','% comments'); ?></a>
                    </div>
                    <div class="clear">&nbsp;</div>
                 </div>
                 <div class="line">&nbsp;</div>
                 <?php wp_list_comments();?>
                 <?php comment_text(); ?>
            </div>
            <!--end item -->
            <?php endwhile; ?>

            <?php endif; ?>

as you can see I’m trying to use <?php wp_list_comments();?> & <?php comment_text(); ?>but none of them work I don’t see any comments and I should see two…
please help
