[support] File directory location in Drupal 6

This is a weird problem... I'm using file_directory_path() as talked about in http://api.drupal.org/api/drupal/includes%21file.inc/function/file_directory... It's not returning the correct location. From www.example.com/location/something it's giving www.example.com/location/path.to.files instead of www.example.com/path.to.files This is pretty weird. Any ideas? Joel
