Problem 2 of code challenge

I've tried this a number of times in different iterations. I don't know what I'm doing wrong here? The problem in the lesson is a little more complicated and I'm missing something in the pairing down of the code challenge, I guess?

Someone please help?

Thanks in advance.

index.php
<?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) { 

          ?>

            <li><?php echo $book " (" . $book[$isbn] .")"; ?></li>
        <?php } ?>
    </ul>
</body>

Check to see if adding the concatenation . in your <li> tag PHP code solves the issue.

<li><?php echo $book . " (" . $book[$isbn] . ")"; ?>

Thanks! I saw that right after I posted the question, but no dice. Still trying to put the pieces together ...

This will get you a correct answer, after I've reviewed the challenge - let me know if something doesn't make sense and I'd be happy to break it down:

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