Modrewrite changes

Hello,

I’ve made a little linkexchange script myself and the url currently is something like =>

/index.php?page_id=14&category=computers&subcategory=advertising-and-marketing

But when i work via the modrewrite like

resource-directory/computers/advertising-and-marketing.html

This =>

RewriteRule ^resource-directory/(.*)/(.*)\.(.*) http://www.health-weightloss-information.com/index.php?page_id=14&category=$1&subcategory=$2 [L]
RewriteRule ^resource-directory/(.*)\.(.*) http://www.health-weightloss-information.com/index.php?page_id=14&category=$1 [L]

Well nothing seems to work what i try because wordpress gives me always an 404 error that the page not could be found.

Can anyone in here help me please?
