BuddyPress.org

Hello all, I’m a newbie in the world of php. I’m want to create a profile using buddypress members. That means I have to add more fields like age, gender, country e.t.c to wp_user in the database. I’ve figured out how to add the fields to the database. Now, my question is “how do I write the php code in member-loop so as to make it display on members page. The default ones available are bp_member_name(); or bp_member_name();. How to I make age, country, phone e.t.c display.
Thank you.
