WordPress Subfolder Issues

Hi, I just uploaded the wordpress files to mydomain.com/staging subfolder. And I added a .htaccess file in the /staging subfolder that contains the following:

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

But when I go to mydomain.com/staging, I get the directory listing. And when I actually go to wp-login.php, it is not styled. Looking at the <link> tags it looks like the styles are trying to pull from mydomain.com instead of mydomain.com/staging.

How do I fix this, so when I go to mydomain.com/staging I get a normal wordpress site?
