Why Isn't This Showing Up?

[Pc 1203]

Hi All (Maybe a Few, again),
Well, I'll just cut to the chase:

Here Is My PHP Code:

PHP Code:

<?php
chdir('/home/penguink/public_html/forums');
require_once('/home/penguink/public_html/forums/global.php');
$userid = $vbulletin->userinfo['userid'];
include ('/home/penguink/public_html/members/header.php');
include ('/home/penguink/public_html/members/nav.php');
If ($vbulletin->userinfo['userid']!=0)
    {    
    echo "<center><h1>UserCP</h1></center>";
    echo "<form action=\"update.php\" method=\"post\">";
    echo "Please enter your username:<br />";
    echo "<input type=\"text\" name=\"name\" value=\"";
    echo $userinfo['field6'];
    echo "\">";
    echo "<p>Please enter your Favorite game:<br />";
    echo "<input type=\"text\" name=\"favgame\" value=\"";
    echo $userinfo['field5'];
    echo "\">";
    echo "<p>Please Enter The Server You Mostly Go On:<br />";
    echo "<input type=\"text\" name=\"server\" value=\"";
    echo $userinfo['field4'];
    echo "\">";
    echo "<p>Please choose a theme:<br />";
    echo "<input type=\"radio\" name=\"theme\" value=\"Default\"> Default
<br>
<input type=\"radio\" name=\"theme\" value=\"Blue\"> Blue
<br>
<input type=\"radio\" name=\"theme\" value=\"Penguin\"> Penguin
<br>
<input type=\"radio\" name=\"theme\" value=\"Penguin\"> Green
<br>
<input type=\"hidden\" name=\"uid\" value=\"";
print $userid;
echo "\">";
echo "<input name=\"Save\" type=\"submit\" />
</form>";
    } else {
    echo "<center><h1>Error!</h1></center>";
    echo "uh-Oh! Please <a href=\"/login.php\">login</a>!";
    }
include ('/home/penguink/public_html/members/footer.php');
?>

When I go to the page that it is on, I get the following (source code)

<input type="text" name="name" value="">

It should have field6 there. Also, yes field6 is filled out for me.
