Collapsible comments plugin.

Hi I am trying to use the collapsible comments plugin and am having an issue with its install.

After placing it in my plugins directory and activating it I am instructed to go to my comments php file and replace <?php comment_text(); ?> with <?php collapsiblecomments(); ?> The only problem being I can’t find a comment_text entry. Here is my comments php

<?php if ( post_password_required() ) : ?>
<p class=”nopassword”><?php _e( ‘This post is password protected. Enter the password to view any comments.’, ‘themify’ ); ?></p>
<?php
/* Stop the rest of comments.php from being processed,
* but don’t kill the script entirely — we still have
* to fully load the template.
*/
return;
endif;
?>

<?php
// You can start editing here — including this comment!
?>

<?php if ( have_comments() || comments_open() ) : ?>
<div id=”comments” class=”commentwrap”>
<?php endif; // end commentwrap ?>

<?php if ( have_comments() ) : ?>
<h4 class=”comment-title”><?php comments_number(__(‘No Comments’,’themify’), __(‘One Comment’,’themify’), __(‘% Comments’,’themify’) );?></h4>

<?php if ( get_comment_pages_count() > 1 && get_option( ‘page_comments’ ) ) : // Are there comments to navigate through? ?>
<div class=”pagenav top clearfix”>
<?php paginate_comments_links( array(‘prev_text’ => ‘«’, ‘next_text’ => ‘»’) );?>
</div>
<!– /.pagenav –>
<?php endif; // check for comment navigation ?>

<ol class=”commentlist”>
<?php wp_list_comments(‘callback=custom_theme_comment’); ?>

<?php if ( get_comment_pages_count() > 1 && get_option( ‘page_comments’ ) ) : // Are there comments to navigate through? ?>
<div class=”pagenav bottom clearfix”>
<?php paginate_comments_links( array(‘prev_text’ => ‘«’, ‘next_text’ => ‘»’) );?>
</div>
<!– /.pagenav –>
<?php endif; // check for comment navigation ?>

<?php else : // or, if we don’t have comments:

/* If there are no comments and comments are closed,
* let’s leave a little note, shall we?
*/
if ( ! comments_open() ) :
?>

<?php endif; // end ! comments_open() ?>

<?php endif; // end have_comments() ?>

<?php
$custom_comment_form = array( ‘fields’ => apply_filters( ‘comment_form_default_fields’, array(
‘author’ => ‘<p class=”comment-form-author”>’ .
‘<input id=”author” name=”author” type=”text” value=”‘ .
esc_attr( $commenter[‘comment_author’] ) . ‘” size=”30″‘ . $aria_req . ‘ class=”required” />’ .
‘<label for=”author”>’ . __( ‘Your Name’ , ‘themify’ ) . ‘</label> ‘ .
( $req ? ‘<span class=”required”>*</span>’ : ” ) .
‘</p>’,
’email’ => ‘<p class=”comment-form-email”>’ .
‘<input id=”email” name=”email” type=”text” value=”‘ . esc_attr( $commenter[‘comment_author_email’] ) . ‘” size=”30″‘ . $aria_req . ‘ class=”required email” />’ .
‘<label for=”email”>’ . __( ‘Your Email’ , ‘themify’ ) . ‘</label> ‘ .
( $req ? ‘<span class=”required”>*</span>’ : ” ) .
‘</p>’,
‘url’ => ‘<p class=”comment-form-url”>’ .
‘<input id=”url” name=”url” type=”text” value=”‘ . esc_attr( $commenter[‘comment_author_url’] ) . ‘” size=”30″‘ . $aria_req . ‘ />’ .
‘<label for=”email”>’ . __( ‘Your Website’ , ‘themify’ ) . ‘</label> ‘ .
‘</p>’) ),
‘comment_field’ => ‘<p class=”comment-form-comment”>’ .
‘<textarea id=”comment” name=”comment” cols=”45″ rows=”8″ aria-required=”true” class=”required”></textarea>’ .
‘</p>’,
‘logged_in_as’ => ‘<p class=”logged-in-as”>’ . sprintf( __( ‘Logged in as %2$s. Log out?‘ ), admin_url( ‘profile.php’ ), $user_identity, wp_logout_url( apply_filters( ‘the_permalink’, get_permalink( $post_id ) ) ) ) . ‘</p>’,
‘title_reply’ => __( ‘Leave a Reply’ , ‘themify’ ),
‘comment_notes_before’ => ”,
‘comment_notes_after’ => ”,
‘cancel_reply_link’ => __( ‘Cancel’ , ‘themify’ ),
‘label_submit’ => __( ‘Post Comment’ , ‘themify’ ),
);
comment_form($custom_comment_form);
?>

<?php if ( have_comments() || comments_open() ) : ?>
</div>
<!– /.commentwrap –>
<?php endif; // end commentwrap ?>

Other plugins I am using are Autohyperlink URLs, MCE comments, WP Comment Master, Simple Local Avatars, and Email Alerts.

I could gues why this is happening but I will leave it to wiser minds to assist. Any help someone could give would be much appreciated.
Thanks!
