adding forum jump to a custom vb3 page

[evil kev]

hey i'm sure this is an easy mod to do i'm just probably missing something obvious.

here's the php code for my page

PHP Code:

<?php
include_once('chat/inc/common.php');

// ####################### SET PHP ENVIRONMENT ###########################
error_reporting(E_ALL & ~E_NOTICE);

// #################### DEFINE IMPORTANT CONSTANTS #######################
define('NO_REGISTER_GLOBALS', 1);
define('THIS_SCRIPT', 'chat'); // change this depending on your filename

// ################### PRE-CACHE TEMPLATES AND DATA ######################
// get special phrase groups
$phrasegroups = array(

);

// get special data templates from the datastore
$specialtemplates = array(
    
);

// pre-cache templates used by all actions
$globaltemplates = array(
    'CHAT',
);

// pre-cache templates used by specific actions
$actiontemplates = array(

);

// ######################### REQUIRE BACK-END ############################
require_once('./global.php');

// #######################################################################
// ######################## START MAIN SCRIPT ############################
// #######################################################################

$navbits = array();
$navbits[$parent] = 'Chat Login';

$navbits = construct_navbits($navbits);
eval('$navbar = "' . fetch_template('navbar') . '";');
eval('print_output("' . fetch_template('CHAT') . '");');

$frmjmpsel['chat'] = ' selected="selected" class="fjsel"';
construct_forum_jump();
?>

and i tried just sticking $forumjump in my template but it just wouldn't appear i guess its because $forumjump hasn't been assigned to anything but i don't know where it would be assigned. any help would be excellent
