WP comment pagination

I am having issues with the comment pagination, the code below throws an error:

Fatal error: Can’t use function return value in write context in /home/monthlyw/public_html/comments.php on line 30

<?php
global $wp_query;
$total = $wp_query->max_num_pages;
// only bother with the rest if we have more than 1 page!
if ( $total > 1 )  {
     // get the current page
     if ( !$current_page = get_query_var('paged') )
          $current_page = 1;
     // structure of "format" depends on whether we're using pretty permalinks
>>     $format = empty( get_option('permalink_structure') ) ? '&page=%#%' : 'page/%#%/';
     echo paginate_links(array(
          'base' => get_pagenum_link(1) . '%_%',
          'format' => $format,
          'current' => $current_page,
          'total' => $total,
          'mid_size' => 4,
          'type' => 'list'
     ));
}
?>

Any help as the codex is a little bare on comment pagination, and Google doesn’t throw up many tuts for the pagination.

I would like my pagination to look the same as my pages pagination which you can see here

<?php paginate_comments_links(); ?> 

EDIT: lets prevent errors

        <?php if ( get_comment_pages_count() > 1 && get_option( 'page_comments' ) ) :  ?>

        <nav class="pagination">

            <?php paginate_comments_links(); ?> 

          </nav>

        <?php endif; ?>

What OrganicBeeMedia said, use http://codex.wordpress.org/Template_Tags/paginate_comments_links

paginate_links() are not for comments.

Thanks guys, my first time creating comment pagination so on a little learning spree

Been modifying the code to my needs but somehow, WP is showing the comments from another post on all the posts.

See here, the meta info says no comments (and shows in the admin area) but comments are being shown:

$comments = get_comments($args, $post->ID);
foreach($comments as $comment) :

 echo '<div class="comment margin30"><div class="avatar">';
 echo get_avatar( $comment, 32 );
 echo '</div><div class="comm-text-wrap"><div class="comm-text"><p style="font-family: Verdana;">';
 echo($comment->comment_author);
 echo '</p><div class="bubble"><div class="bubble-bg" /><p>';
 echo($comment->comment_content);
 echo comment_reply_link( $comment );
 echo '</p></div></div></div></div>';

endforeach;
unset($comments);

$num_comments = get_comments_number();

if ( comments_open() ) {
 if ( $num_comments == 0 ) {
  $comments = __('No Comments', 'your_text_domain');
 } elseif ( $num_comments > 1 ) {
  echo '<div class="pagination">';
  paginate_comments_links(); 
  echo '</div>';
 }
}

echoing $num_comments gives me the total of 0 comments

Any help is appreciated

Add wp_reset_query(); on top of that code you pasted.

All sorted, rewrote the comment function and found the error, now works a charm
