[Quarterbore]

I have a situation where I also need to convert a USERNAME from a template to a USERID inside a main php file....

I tried to use the code above in my file like this:

$getuser = $vbulletin->db->query("
 SELECT userid,username
 FROM myuser
 WHERE username = $username
");
$user = $DB_site->fetch_array($getuser);
echo("The userid for $user[username] is <b>$user[userid]</b>");

I know my post is getting the correct $username into this but I am getting a MYSQL error that says...

Database error in vBulletin 3.5.2:

Invalid SQL:

SELECT userid,username
FROM XXXXXXXXXX
WHERE username = Quarterbore;

MySQL Error : Unknown column 'Quarterbore' in 'where clause'
Error Number : 1054

Referrer : http://www.XXXXXXXXXX.com/XXXXXXXXXX.php?do=ad&id=50
IP Address : XXX.XXX.XXXX
Username : Quarterbore
Classname : vb_database

I just can't finish my minor addition until I can get this basic change of $username into $userid

I would really appreciate any help!
