Bug or wrong code

I'm having alot of trouble getting through these tasks, it keeps saying "Oops! It looks like Task 1 is no longer passing.". I'm using the following foreach loop:

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

It's because you are no longer displaying the title.
In Step one it had ?php echo $book; ?> . Which just echoed the title. Here you have erased $book (which means that that task 1 no longer works) and only display the ISBN. Make sure you have the title followed by a space and then the ISBN in parenthesis.

Thank you very much for your help, I completely overlooked the "AFTER the title..." :)
