Mod Rewrite Help

I need help turning this

http://bob.url.com/bob/index.php?id=abc

into this

http://bob.url.com/bob/abc/

I tried this and it's not working at all.

RewriteEngine On
RewriteRule ^([^/\.]+)/([^/\.]+)/?$ $1/index.php?id=$2 [L]

Code (markup):

Thanks!

RewriteRule ^bob/([^.]+)/$ bob/index.php?id=$1 [L]
