Hi Chetan,

Try changing the following:

        <?php foreach($books as $isbn => $book) { ?>
            <li><?php echo $book; 
                      echo ' ('.$isbn.')';
                 ?>
             </li>
        <?php } ?>

to:

        <?php foreach($books as $isbn => $book) { ?>
            <li><?php echo $book . ' (' . $isbn . ')'; ?></li>
        <?php } ?>

Hope that helps
