Can't figure out what I'm doing wrong here..

This code is supposed to load the book title and the ISBN #. Treehouse says it only loads title. What do I need to add?

<?php

$books["978-0743261690"] = "Gilgamesh"; $books["978-0060931957"] = "The Odyssey"; $books["978-0192840509"] = "Aesop's Fables"; $books["978-0520227040"] = "Mahabharta"; $books["978-0393320978"] = "Beowulf";

?><html> <head> <title>Five Great Books</title> </head> <body> <h1>Five Great Books</h1> <ul> <?php foreach($books as $book => $isbn) { ?> <li><?php echo $book; ?></li> <?php } ?> </ul> </body> </html>
