PHP Build a Basic PHP Website (2018) Listing and Sorting Inventory Items Array Keys

Test: "Check Work" questionable & "Preview" 404'ing

Hi, the test for https://teamtreehouse.com/library/build-a-basic-php-website/listing-and-sorting-inventory-items/array-keys

"Preview" result is a 404. Code I work with on my own server checks out, but "Check work" fails every time.

My code: <?php foreach($books as $id => $book) { ?> <?php $isbn = $id; echo $isbn; ?> <li><?php echo $book; ?></li> <?php } ?>

Thanks anyone, everyone. Steve

        <?php } ?>

I had this initially & assigned $isbn = $id which works technically, but is longer & not a passable answer. <?php foreach($books as $id => $book) { ?>

Correct: <?php foreach($books as $isbn => $book) { ?>
