Pages showing up as index.php?id= Children

[mrprez8]

Hey everyone, I just got started with GS today, and I'm really enjoying the flexibility.However, I have a problem. I don't exactly know how the get_navigation(); function works. When I create new pages, they show up as index.php?id=thepage children almost. For example, I have a home page that is accessible via the navigation menu:

Code:

<div id="nav">
<?php get_navigation(); ?>
</div>

Another, separate, page, though, called Events, doesn't show up in the navigation menu and is only accessible via:

Code:

mysite/index.php?id=events

How do I fix this problem so all my pages show up in the navigation?!

Any help would be appreciated,
Nick
