Courses Plus Student 10,585 PointsThat code is valid, that warning is being generated because the function is unable to find the "category" key from the catalog array. This leads me to believe that when you are calling the function it cannot find the catalog array from data.php.
We would really need to see the other code from the other files you have to tell you exactly what is wrong, but my best guess would be that you might not have data.php included in your catalog.php file. Make sure right below the "<?php" at the top you have both of these lines of code:
include("inc/data.php");
include("inc/functions.php");
