Whats wrong with my PHP script?

[Jack B]

I cant seem to be able to read from MYSQL, much less set the result as session variables...

Heres my code:

session_register('user');
session_register('pass');
$getinfo="SELECT * FROM users WHERE login_name='" . $user . "'";
$info=mysql_query($getinfo);
$_SESSION['id'] = $info['user_id'];
$_SESSION['user'] = $info['username'];
$_SESSION['avatar'] = $info['avatar'];
$_SESSION['access_lvl'] = $info['access_lvl'];
$_SESSION['pass'] = $pass;
