hiding pages

Hi, I need to create a page, but have it hidden from the navigation. I’m trying to use the exclude parameter, but can’t seem to figure out how to work it. When I try to use it, it messes up my entire site.

Here’s what it looks like right now with the exclude parameter placed:

<?php wp_list_pages(‘title_li=&depth=1’; exclude=17,38;); ?>

Any help would be great,
thanks in advance!
