Code Challenge Incorrect?? PHP, array, foreach, key, value.

My preview is showing this code correctly, so am I not passing this challenge?

The question: "Next, modify the code inside the foreach loop to display the $isbn in parentheses. After the title, add a space, an opening parenthesis, the ISBN, and a closing parenthesis."

The error: "Bummer! I see all the book titles and the ISBNs in the browser, but the formatting is not quite right. Each list item should look like this: Book Title (978-0123456789)"


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

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

I figured it out... it was the space after the PHP and before the /li

gotta be careful with the tiny details
