Issue: Profile Privacy

^^;
Sorry. Err.. at first I wanted to put the profile under private so that only friends can view it but somehow I got so confuse setting up the Profile Privacy, that it ended up ~ like blocking everyone (including 'friends').

I tried selecting everything to 'Everyone' but it still block out the friends.
& right now everything is selected as 'Your Contact', which also block out still. What am I doing wrong?

& what does 'Permission Groups' used for?

Didnt know where else to ask so I hope this is okay place to be asking this. Thanks
