CSS Help – Customizing <?php comment_text() ?>

I’m having trouble customizing the CSS for <?php comment_text() ?> in the comments field.
Here’s the link http://michaelclements.co.uk/2009/06/26/2095/
Basically I want to pull the Author/time/date line and the actual comment closer together. I have tried to style it, with no luck…
Here’s the comments php
<ol class=”commentlist”>
<?php foreach ($comments as $comment) : ?>

<li class=”<?php echo $oddcomment; ?>” id=”comment-<?php comment_ID() ?>”>

<div class=”commentmetadata”>
<h4><?php comment_author_link() ?>. <?php _e(‘Posted ‘);?><?php if(!function_exists(‘how_long_ago’)){comment_date() . ‘ at ‘ . comment_time(); } else { echo how_long_ago(get_comment_time(‘U’)); } ?> <?php edit_comment_link(‘Edit Comment’,”,”); ?>
<?php if ($comment->comment_approved == ‘0’) : ?></h4>
<?php _e(‘Your comment is awaiting moderation.’); ?>
<?php endif; ?>
</div>
<?php comment_text() ?>

<?php /* Changes every other comment to a different class */
if (‘alt’ == $oddcomment) $oddcomment = ”;
else $oddcomment = ‘alt’;
?>

<?php endforeach; /* end for each comment */ ?>

and here’s the comments CSS styling
/* comments template */

.comments-template{
margin: 30px 0 0;
padding: 0px 0 0;
border-top: 0px solid #ccc;
}

.comments-template ol{
margin: 0px 0 0;
padding: 0px 0 0;
list-style: none;
}

.comments-template ol li{
margin: 20px 0 0px;
padding: 0px 0 0px;
border-bottom: 0px solid #ccc;
}

.comments-template h3, .comments-template h2{
padding: 0px 0 0;
}

.commentmetadata{
font-size: 12px;
margin: 0px 0 0;
padding: 0px 0 0;
}

/* end comments template */

Any help????
