Excluding a page in WP nav list

[AHA7]

Hello,

My WP theme uses the following code to display the top nav links: <?php wp_list_pages('title_li=&depth=1&'.$page_sort.'&'.$pages_to_exclude)?>

How can I exclude a page using this function?
Do I just add ID of the page I want to exclude after the $pages_to_exclude, example: $pages_to_exclude='7' or what?

Try this:
wp_list_pages('exclude=1,2,3,4,5,6&title_li=&depth=1&'.$page_sort)?>

Just type in each page number you want to exclude. Use a comma to seperate multiple pages.
