Help with login on non-vb page.

I am trying to use the following script by including it into my home page (which has other included items, as well...such as new posts, etc.). However, I get an error whenever I include it.

The Script:
[PHP]
<?

// File: Homepage Login
// Version: 1.0
// By: RobAC
// Date: 7/24/01
// Source: Original VB Homepage Login by Demolition
// Reference: http://www.vbulletin.com/forum/showt...threadid=22192

require("/home/newbeetle/public_html/vbulletin/global.php");

if ($bbuserinfo['userid']!=0) {
$username=$bbuserinfo['username'];

print("<p align='center'>Welcome back,<br /> <b>$username!</b></p>");
print("<p align='center'><b>[ <a href='forums/index.php'>Enter</a> ]</b></p>");

} else {

?>
<form action="http://forums.newbeetle.org/member.php" method="post" />
<input type="hidden" name="s" value="$session[sessionhash]" />
<input type="hidden" name="action" value="login" />
<table width="100%" cellpadding="0" cellspacing="0" border="0">
<tr>
<td align="left"><font class="verdana, arial, helvetica" size="1"><b>Username:</b></font></td>
<td align="left"><input type="text" name="username" size="7" /></td>
</tr>
<tr>
<td align="left"><font class="verdana, arial, helvetica" size="1"><b>Password:</b></font></td>
<td align="left"><input type="password" name="password" size="7" /></td>
</tr>
<tr>
<td align="center" colspan="2"><input type="submit" value="Login!" /></td>
</tr>
</table>
</form>
<?

}

?>
The error:

PHP Code:

Warning: Cannot add header information - headers already sent by (output started at /home/newbeetle/public_html/testindex.php:7) in /home/newbeetle/public_html/vbulletin/admin/functions.php on line 1490 


I have tried it with and without the requires at the begining of the script (global.php and config.php)

You can see it in action (or NOT in action, as it stands) at:

http://newbeetle.org/testindex.php

Any help would be wonderful.

Thanks so much!
