Is this using your own backend or vBulletin's? (I'm guessing your own) You will need to query the database for the user's row and output the information.

PHP Code:

$result = mysql_query("SELECT * FROM `YOURUSERTABLE` WHERE `userid` = " . $YOURUSERIDVARIABLE . " LIMIT 1");
$row = mysql_fetch_assoc($result); 


Then all your information would be in $row. To access it's data, simply use $row['FIELD'] (where FIELD is the name of the required field).
