admincp is blank after adding code...

When I do this part:

::: Open File - ROOT FORUM DIRECTORY/admincp/index.php
 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
 FIND:
 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
 	// *************************************************
 
 	$printhr = false;
 	if (can_administer('canadminsettings'))
 	{
 		$printhr = true;
		construct_nav_option($vbphrase['vbulletin_options'], 'options.php?null=0', '<br />');
 		if ($debug == 1)
 		{
			construct_nav_option($vbphrase['admin_help_manager'], 'help.php?do=manage&script=NOSCRIPT');
 		}
 		construct_nav_group($vbphrase['vbulletin_options'], '<hr />');
 	}
 	if ($printhr == true)
 	{
 		construct_nav_spacer();
 	}
 
 	// *************************************************
 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
 UNDERNEATH ADD:
 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
 	$printhr = true ;
 	construct_nav_option ( 'vBChat Options', 'admin_vbchat.php', '<br />' ) ;
 	construct_nav_option ( 'Banned Usergroups', 'admin_vbchat.php?do=banned_groups', '<br />' ) ;

 	construct_nav_option ( 'vBChat Prune Options', 'admin_vbchat.php?do=prune', '<br />' ) ;
 	construct_nav_group ( 'vBChat Control', '<hr />' ) ;
 	$printhr = false;
 
 ::: Save & Reupload ROOT FORUM DIRECTORY/admincp/index.php

My admincp doesnt load up, it just gives me a blank white page. When I revert to the old admincp, it's fine. What's up?

Are you adding the right section? In the right place?
