Recommendations/help with 'Add Contact List'

Question

hello,
i've run into a bit of a problem, need some expert advice
before i lose my mind :)...
i am trying to allow registered users to have a friend list.
my problems:
1) user is viewing their friend list and only their friends
user_id shows up rather than their friends username...
Here is the SQL i have as of now:
SELECT userTable.user_id, userTable.username,
friendTable.user_id, friendTable.them_user_id
FROM userTable JOIN friendTable ON userTable.user_id =
friendTable.user_id
WHERE userTable.username = var1($_SESSION['MM_Username']
2) when users click 'add friend' button (which is an insert
form with 3 hidden fields, user_id, friend_id, MM_insertform), my
code doesn't check if they are already friends with that person...
not a huge deal, but i'd like to have this feature if i can...
i'd be thankful for any advice, help, etc... thank you!

var1($_SESSION['MM_Username']
what happens if you include friendTable.username in the SQL
statement?
>=20

There is a built in server behavior for Check Username that
will check =
for an existing user name. You might be able to modify that
to meet =
your needs. Keep in mind that modified code will work but
disappear =
from the Bindings/Server Behaviors panel.
