Hi Naif

Most of your $_GET["cat"] don't have the underscore (you have $GET["cat"]) - the only one where it is correct (movies), you misspelt "movies" as "moives" in the $section="moives"; code.

The correct code is:

if (isset($_GET["cat"])) {
    if ($_GET["cat"] == "books") {
        $pageTitle = "Books";
        $section = "books";
    } else if ($_GET["cat"] == "movies") {
        $pageTitle = "Movies";
        $section = "movies";
    } else if ($_GET["cat"] == "music") {
        $pageTitle = "Music";
        $section = "music";

Hope that helps!


Thank you so much appreciate it :)
