Thanks for finally posting your code. In your index, above include, add this - $section = "home";

Hi Mark,

Are you defining $section before including header.php on each page?

<?php
$pageTitle = "Mike's Full Catalog of Shirts";
$section = "shirts";
include('./inc/header.php');
?>

Try removing the semicolon 

<?php echo $pageTitle; ?>

to

<?php echo $pageTitle ?>

If that doesn't help. Let us know.

Hello Gloria,

Unfortanly It didn't helped. I still get the same error messages on the index page. The contact and the shirts page are working fine.

It looks like your issue is you have not defined the variable $section anywhere. So PHP is trying to test your if statement, but can't find $section so it is printing out an error.

If you show me both your index.html code and your full header.php code I may be able to figure out exactly where this definition is failing.

You have not defined $section in your index.html file, and this is why you are getting an error. Right below $pageTitle = "Unique T-shirts designed by a frog"; type $section = "shirts";. This should fix your problem.
