I too have a the same question (and to be honest, as I started chapter 8, I began to feel out of my league - so I am in severe need of step by step instructions come this chapter until some of these concepts hit home)
Here is what I have - my view_settings php file looks like this (which I got help from this forum) and it is not working:
<style type="text/css">
body {
<?php // Pursue # 9 - Customize rewrite - view_settings.php
// Check for a font_size value:
if (isset($_COOKIE['font_size'])) {
print "\t\tfont-size: " . htmlentities($_COOKIE['font_size']) . ";\n";
} elseif (isset($_POST['font_size']) {
print "\t\tfont-size: " . htmlentities($_POST['font_size']) . ";\n";
} else {
print "\t\tfont-size: medium;";
}
// Check for a font_color value:
if (isset($_COOKIE['font_color'])) {
print "\t\tcolor: #" . htmlentities($_COOKIE['font_color']) . ";\n";
} elseif (isset($_POST['font_color']) {
print "\t\tcolor: #" . htmlentities($_POST['font_color']) . ";\n";
} else {
print "\t\tcolor: #000;";
}
?>
}
</style>
</head>
<body>
<p><a href="customize.php">

<p><a href="reset.php">Reset your Settings</a></p>

My customize looks like this:
<?php // Script 9.1 - Cutomize.php
// Handle the form if it has been submitted:
if (isset($_POST['font_size'], $_POST['font_color'])) {
// Send the cookies:
setcookie('font_size', $_POST['font_size'], time()+1000000, '/', '', 0);
setcookie('font_color', $_POST['font_color'], time()+1000000, '/', '', 0);
//Message to be printed later:
$msg = '<p> Your settings have been entered! Click <a href="view_settings.php"> here</a> to see them in action.</p>';
} // End of submitted IF.
