Theme’s Comment Form

I think this theme I am using has a lot of stuff missing and the author is gone. I’ve fixed most of the stuff but I have no idea how to fix it so the comment form has the information saved after the person comments.

<?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"><?php _e("This post is password protected. Enter the password to view comments."); ?><p>

				<?php
				return;
            }
        }

		/* This variable is for alternating comment background */
		$oddcomment = "graybox";
?>

<!-- You can start editing here. -->
<div id="comment-item">
<div id="hasil-comment">
<?php if ($comments) : ?>

<?php comments_number('No Comments', 'One Comment', '% Comments' );?> to “<?php the_title(); ?>”

		<li class="<?=$oddcomment;?>">

			<?php comment_text() ?>

		</li>

		<?php /* Changes every other comment to a different class */
			if("graybox" == $oddcomment) {$oddcomment="";}
			else { $oddcomment="graybox"; }
		?>

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

	</ol>

 <?php else : // this is displayed if there are no comments so far ?>

  <?php if ('open' == $post-> comment_status) : ?>

	 <?php else : // comments are closed ?>
