HTML of WordPress Page being converted

I wanted to make a Page that displayed links in categories. So I went to add a new Page and clicked on the HTML button, to add this:

<ul>
<?php get_linksbyname('Friends', '<li>', '</li>', '<br />', FALSE,
'name', FALSE, TRUE); ?>
<li><a href="http://happymess.net/d/links" alt="Find more exits">More links
here</a></li>
</ul>

But when I view the page (after saving, of course) it is converted to this: (!!!!)

<!--p get_linksbyname('Friends', '
‘, ‘
‘, ‘
‘, FALSE, ‘name’, FALSE, TRUE);–>

Why does it do this? I thought Pages could do anything. Here’s the link to the page: http://happymess.net/d/links

Thank you in advance for any help.
