How do I change the path to the style.css file?

Hi!

I just immigrated to WordPress from Blogger.
I wanted to make sure, I could import my Blogger blogs, so I installed WP in a “wordpress” folder on my site.

After some tries I finally managed to import the entries, so I wanted to go all the way, and start using WP for real.

I managed to change my URL using mySQL, but in the process I found that I had to copy the content of the “wordpress” folder to the root of the site – or so I thought.
After trying to manipulate the template files today, I discovered that the active files still are the ones inside the “wordpress” folder, except for the style.css file.

So in short:
I have my WP blog at: http://www.floede.dk
My template files are located in: floede.dk/wordpress/wp-content/themes/green-marinee/

But the CSS file being used is in:
floede.dk/wp-content/themes/green-marinee/

I actually like that everything is placed inside the “wordpress” folder.
But I simply don’t know enough PHP to figure out why the css path is different from the template path.

So can anybody tell me in which file, and line I change this?
