Cannot get username

[LjTiger69]

Hello, I'am new in VB4.
I try to create a plugin that add a field in postbit for showing a score from a game. This field is stored in a custom table in db.
This is code for plugin:

$name = $vbulletin->userinfo['username'];
$sql = "SELECT * FROM record WHERE Nome='$name'";
$result = mysql_query($sql);
$row = mysql_fetch_assoc($result);

if ($row[Record])
{
    $template_hook['postbit_userinfo_right_after_posts'] .= '<dt>Score</dt> <dd>' .$row[Record]. '</dd>';
}

Problem is that $name return ""
How can get the username?

Try including..

global $vbulletin;

As the first line in your plugin code.
