Login from external page problem.

[gamesxposed]

On my external page I have this:

chdir("forums/");
require('./global.php');

And:

<?
$username=$vbulletin->userinfo['username'];
print("$username");

if ($vbulletin->userinfo['userid']!=0) {
/*$username=$vbulletin->userinfo['username'];*/

print("<align='center'><span class='sectionheader'>Welcome back, $username!<br /><br />");
print("<a href='/forums/login.php?$session[sessionurl]do=logout&amp;u=$vbulletin->userinfo[userid]'>. <b>Log out</b></a><br />");
print("<a href='/forums/search.php?do=getnew'>. <b>New Posts</b></a><br />");
print("<a href='/forums/search.php?'>. <b>Search Forums</b></a><br />");
print("<a href='/forums/usercp.php?'>. <b>My Profile</b></a><br />");
print("<a href='/forums/private.php?'>. <b> Private Messages</b></a>");


} else {


?>


<form action='/forums/login.php' method='post' onsubmit='md5hash(vb_login_password,vb_login_md5pa ssword)'>
<script type='text/javascript' src='/forums/clientscript/vbulletin_md5.js'></script>

<span class="sectionheader">Username:</span><br />
<input type='text' class='button' name='vb_login_username' id='navbar_username' size='15' accesskey='u' tabindex='1' value='' onfocus='if

(this.value == 'username') this.value = '';' /><br>

<span class="sectionheader">Password:</span><br />
<input type='password' class='button' name='vb_login_password' size='15' accesskey='p' tabindex='2' /><br>
<input type='checkbox' name='cookieuser' value='1' tabindex='3' id='cb_cookieuser_navbar' accesskey='c' checked='checked' /><span

class='sectionheader'>Remember Me</span><br /><br />



<input name="submit" type='submit' class='button' accesskey='s' tabindex='4' title='Log in' value='Log in' />
<input type='hidden' name='do' value='login' />
<input type='hidden' name='forceredirect' value='1' />
<input type='hidden' name='vb_login_md5password' />
</form>
<br />Not registered? <a href="/forums/register.php?"><b>Register here!</b></a>

<?

}

?>

However, when the user logs in and returns to the external page, it doesn't show them as logged in. How am I able to get it to see if they are logged in or not and show the correct data? I had it working on 3.0 Perfectly, just on 3.5 it no longer returns if they are logged in or not and just keeps the "login" box there.

Thanks.
