Hey Paul,

I think you may have got a tad off course for the task. Task 1 just wants you to modify the for each loop so that it also grabs the ISBN as well as the title. I'm not sure why you have a GET in there with a Hard-Coded index?

All you need for the first task is a simple addition to the loop to also grab the ISBN using the => symbol. Below is the corrected code for Task 1. I hope it will make sense now.

<?php

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

?><html>
<head>
    <title>Five Great Books</title>
</head>
<body>
    <h1>Five Great Books</h1>
    <ul>
        <?php foreach($books as $isbn => $book) { ?> <!-- This is the only line that needs to be modified for Task 1 -->
            <li><?php echo $book; ?></li>
        <?php } ?>
    </ul>
</body>
</html>

Hey Jason, I am a little off and it looks like I made this a little more complicated than it needs to be. This makes perfect sense, thank you.
