Need help with rewrite rule

For 2 days now, I've been trying to convert forumdisplay.php?f=63 to forumdisplay.php?f=1 but nothing works.

Last one I tried was:

RewriteRule ^forumdisplay.php?f=63/$ forumdisplay.php?f=1 [L,R=301]

What am I doing wrong?

 

Try with the following code

Options +FollowSymLinks
RewriteEngine On
RewriteRule ^forumdisplay.php?f=63$ [url]http://yourwebsite.com/forumdisplay.php?f=1[/url] [R=301,L]

Code (markup):

 

Thanks Rose Hosting. I tried it but it still doesn't work...
