301 htaccess www redirect not working

[gatorenvy]

I am trying to set up:
gatorenvy.com/forums/index.php to redirect to
www.gatorenvy.com/forums/index.php but it is not working.

I placed this in the .htaccess in /forums/ where I have VB installed.

Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^gatorenvy.com/forums [nc]
rewriterule ^(.*)$ http://www.gatorenvy.com/forums/$1 [r=301,nc]

I have wordpress installed in my root and it is redirecting fine.

Any thoughts?
