Cannot block an Url Group with Membership

Hi, I have a problem with blocking an url group on my site for Visitors. I made a group and entered 3 http links for example:
http://www.nextx.se/guld_kronan/template1
http://www.nextx.se/guld_kronan/template2
http://www.nextx.se/guld_kronan/template3
and putted the group in Access levels for Visitor in Negative Rules and still the link is open for everybody? Do You have an idea?
