<?php
$books["978-0743261690"] = "Gilgamesh";
$books["978-0060931957"] = "The Odyssey";
$books["978-0192840509"] = "Aesop's Fables";
$books["978-0520227040"] = "Mahabharta";
$books["978-0393320978"] = "Beowulf";
?>
Five Great Books ($isbn) Five Great Books
<?php
foreach($books as $isbn => $book) {
?>
<?php echo $books[$isbn] ?>
<?php
}
?>

4,442 PointsIt looks like you might be forgetting the HTML elements. Here's the correct answer, but I HIGHLY recommend you understand what it's doing before you move on. I'm not sure why you're trying to reference $books[$isbn]. The question is trying to get you to display the ISBN, but what you're doing is using the ISBN to display the title. All you need to do is echo out both the $isbn and $book variables separately (in their proper HTML elements).
Cheers!

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

Courses Plus Student 13,164 PointsI also agree with Mike that you need to make sure you understand each section before you move on. I would suggest watching the video and giving it another shot. Good luck!
