The important thing about the conditional I gave you is it only works in posts/the postbit.

You could show it to admins OR the user who's viewing his own post with:

<vb:if condition="($bbuserinfo['userid'] == $post['userid']) OR (is_member_of($bbuserinfo, 6))">

Where 6 is the usual usergroup for admins.

But the fact your mentioning fields makes me think this code isn't for the postbit.

If you're using custom profile fields you can mark them as private to limit who sees them.
