Comments don’t submit in Internet Explorer. -.-

Ugh. Okay so here’s the deal. I just set up a nice new template and everything was going great! I’ve been using WordPress for quite some time now and feel pretty knowledgeable about everything… However I have bumped into a problem, and I’m having trouble… Any help would be greatly appreciated.

Here’s the deal. When I go to submit a comment in Firefox I have no problem. A user alerted me that their comment wouldn’t submit, and after checking anything in moderation I realized that when you hit the submit button in IE nothing happens.

Here is my comments.php code, anything else you need that can help me resolve this I can provide. Thank you!

<?php // Do not delete these lines
	if ('comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
		die ('Please do not load this page directly. Thanks!');

	if (!empty($post->post_password)) { // if there's a password
		if ($_COOKIE['wp-postpass_' . COOKIEHASH] != $post->post_password) {  // and it doesn't match the cookie
			?>

<p class="nocomments">This post is password protected. Enter the password to view comments.

<?php
			return;
		}
	}

	/* This variable is for alternating comment background */
	$oddcomment = 'class="alt" ';
?>
<!-- You can start editing here. -->
<?php if ($comments) : ?>
<?php if (!('open' == $post-> comment_status)) : ?>
<span class="closecomment">
<?php _e('Comments are closed')?>
</span>
<?php else : ?>
<?php endif; ?>

<h3 id="comments">
  <?php comments_number('No responses', 'One response', '% responses' );?>
  <?php _e('so far')?>, <a href="#respond"><?php _e('want to say something?')?></a>

<ol class="commentlist">
  <?php foreach ($comments as $comment) : ?>

EDIT: I realize that it might help to also have a link to my site so here you go: http://damienk.com/brand-new-look-340/ Submitting a comment in IE on that page (or any other) does not work…
