php array not working

This is my first foray into customizing the WP comment form, and it's giving me a bit of trouble. Ideally, I'd like to have a comment form with 3 fields: Name, Location, and Comment. To facilitate that, I'm using arrays:

<?php comment_form(array(
    'title_reply'=> 'Please feel free to share your home owning hopes and dreams.',
    'fields' => apply_filters( 'comment_form_default_fields', $fields ),
    'label_submit' => 'Share',
    )); 
    ?>

In the comment list, I want the comment to display and just below that have "Name | Location"

<div class="comment-content"><?php comment_text(); ?><?php comment_author(); ?> | <?php echo $comment_author_url ?> </div>

As you can see on the live site, it isn't quite coming out that way. Any ideas why that may be? Tips and insight are appreciated.
