$books["978-0743261690"] = "Gilgamesh";
$books["978-0060931957"] = "The Odyssey";

    <h1>Five Great Books</h1>
        <?php foreach($books as $isbn => $book) { ?>
            <li><?php echo $book ?></li>
        <?php } ?>

Hello Philip,

All you need to do is to add parenthesis and echo the $isbn variable inside them inside the list item. Like this:

<li><?php echo $book; ?> (<?php echo $isbn ?>)</li>
