I think I did everything Alena showed in this video but I can't filter items by category

In this video we filter our items by categories based on the section variable values associated with each page (books page, videos pages, music page, etc).

I encounter 2 problems:

  1. The categories don't work, moreover, the pages are empty from items.

  2. The music page has an error "unidentified variable - pagetitle"; This is wired as I just tried to put it's H1 similar to the default pagetitle.

Here is my site:

To address your page title variable, you have a double equals sign on top of you catalog.php when you are assigning the value to the $pagetitle variable, so I'd start with putting a single equals sign for 

$pagetitle = "music";

Indeed putting a single equal-sign vanished the "unidentified variable" error. You might have an insight on why my items won't appear in each category page?

Hi Ben,

I would recommend that you review the video. Your array_category function is not complete.
