I am totally lost
Cannot figure out Array Keys 2 part Challenge in the Build a Basic PHP series. Any help would be appreciated

I wish I knew what you'd tried that was failing. Because you passed the first step, my gut instinct is to say that maybe you missed the part in the instructions where it said to add open and closed parentheses around the ISBN number. But I really have no idea. Here is the echo line that you need:
<li><?php echo $book . "(" . $isbn . ")"; ?></li>
Hope this helps!
