mod_rewrite - can't figure this out!

Hi,
I am new to php and have to do a project that consists of a joke page, a jokelist page and the front page or index page. My problem is this: I have used the text below in my .htaccess page and the only thing I get when I run the index.php file is the list of joke categories which is right but when i click on a category it produces an not found error.
I am so confused, please can someone help!

RewriteEngine On
RewriteRule^/jokespage$ index.php

RewriteRule ^jokespage/([a-z\-]+).htm$ index.php?jk=$1
