Show more on pages – ajax-styled

Hi,

Im playing with the idéa to have contact forms on specific pages.
I would love to show these with some kind of ajax-style. When i press “Contact us” The page should slide down and then present contact forms. When pressed again, they should collaps.

The problem is that i have no clue how to do this. My “read more” function does not work on pages.

Yes, i have added the code, but still does not work.
<?php global $more;
$more = 0; ?>
Only thing that happens is that i get #more-25 added in the end of the URL when pressed once.

Does anybody have any tips or ideas?

Thanks a ton
