Error in code, but I don't see where

I’m trying to create an admin options page, but I’m getting a syntax error report, but I don’t see how it is a problem.

So, I’m hoping one of you whizzes will see the problem 🙂

I’ve taken the code from the Codex:
http://codex.wordpress.org/Adding_Administration_Menus

The line that seems to be causing the problem is this one:

function mt_add_pages() {

I say that because removing the line removes the error.

This is the code I’m using, including that line, and it tells me the error is on the closing of the PHP at the end.

<?php
// Hook for adding admin menus
add_action('admin_menu', 'mt_add_pages');

// action function for above hook
function mt_add_pages() {

// Add a new submenu under Settings:
    add_options_page(__('Test Settings','menu-test'), __('Test Settings','menu-test'), 'manage_options', 'testsettings', 'mt_settings_page');

// mt_settings_page() displays the page content for the Test settings submenu
function mt_settings_page() {
    echo "<h2>" . __( 'Test Settings', 'menu-test' ) . "</h2>";
}
?>

I’m trying to create a menu item under the settings menu in admin.

Thanks.
