[support] url alias not working?

[will hall]

hi i am trying to make this url (which is linked in a lot of places)

www.freedom-center.org/radio

go to this url on our drupal install

www.freedom-center.org/section/radio

i tried to do this under set url aliases here:

  Existing system path:  http://freedom-center.org/section/radio
Specify the existing path you wish to alias. For example: node/28, 
forum/1, taxonomy/term/1+2.
http://freedom-center.org/radio
Specify an alternative path by which this data can be accessed. For 
example, type "about" when writing an about page. Use a relative path 
and don't add a trailing slash or the URL alias won't work.

but it doesn't seem to work?

thanks for help
