Forum question about variables
 

this link (used for activate an account):
register.php?a=act&u=$userid&i=$activateid

fills $userid automatically...when user press that link..

how can i do the same with this link?:
miembros-$userid-albums.html

(its a vbseo link..to see each users album who is login)
i put that link on the navbar, but $userid variable is not replace :(
