I screwed up my .htaccess file! Please help?

I’m using wordpress 2.3.2 and when I tried to follow the steps here: http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory , I totally screwed everything up.

So now i’ve tried to revert back to the way it originally was but I don’t think I fully fixed the changes I made to the .htaccess file:

Please help!

here’s my .htaccess file as of right now:

“

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wp
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ./wp/index.php [L]
</IfModule>

# RewriteCond %{HTTP_HOST} ^tierzerodivision.com$ [OR]

RewriteCond %{HTTP_HOST} ^.*$
RewriteRule ^/?$ http://tierzerodivision.com/wp [R=301,L]

RewriteCond %{HTTP_HOST} ^thelaf.net$ [OR]
RewriteCond %{HTTP_HOST} ^www.thelaf.net$
RewriteRule ^(.*)$ http://www.tierzerodivision.com/wp [R=301,L]

“

The main changes I originally made were removing the “/wp/” instances from the file including where it said: “tierzerodivision.com/wp”

Now i’ve tried to re-include the “/wp” but I don’t think I’ve done it right

I know it was originally close to the way it is written right now (above) but there must still be a mistake. Can anyone tell me what part I need to fix?
