can you post the code your are using, just because the output looks correct doesnt necessarily mean the code is what the challenge engine is looking for.

yea sure, here is the code


$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 $book ."&nbsp;" ."(" .$isbn .")" ?></li>
        <?php } ?>

It spits out 2 errors, one that code is fine but format isn't correct, and the other i mentioned above.

You really dont need to use a no blank space here. just put a space in the quotes and it works. Although it renders fine in the browser, the challenge engine must not be accepting it for some reason. Use

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


It worked! Phew!, i thought i was doing it wrong, i am not that bad after all. :D
