Form Validation: How to Use a Page Bookmark?

[eluser]Glowball[/eluser]
I have a page with a form far at the bottom of the page. When it goes through its validation, I'd like the resulting page to scroll down to the bottom, like so:

http://www.mysite.com/page#bottom

How do I set this up? I want it to go there no matter what, if the submission passes validation or not.

Thanks!
