rawphrase in custom php file

[aminp30]

thank you Scandal for reply
yes I did.
as you said, I add phrase group in my php file but it dosn't work yet. please take a look at my code:

<?php
error_reporting(E_ALL & ~E_NOTICE);
define('THIS_SCRIPT', 'questions');
define('CSRF_PROTECTION', true);  
$phrasegroups = array('global');
$specialtemplates = array();
$globaltemplates = array('questions');
$actiontemplates = array();
require_once('./global.php');
require_once('./includes/functions.php');
// #######################################################################
// ######################## START MAIN SCRIPT ############################
// #######################################################################
$allow= array(5,6,20,27);
if(in_array($vbulletin->userinfo[usergroupid], $allow) == 0){ print_no_permission(); }
$navbits = construct_navbits(array('' => $vbphrase['questions']));
$navbar = render_navbar_template($navbits);
$pagetitle = 'Questions';

$templater = vB_Template::create('questions');
$templater->register_page_templates();
$templater->register('navbar', $navbar);
$templater->register('pagetitle', 'questions');
print_output($templater->render());
?>

and part of my second php code is:

<form action="" method="get"><div class="datagrid"><table>
<thead><tr><th>{vb:rawphrase quiz_question_text}</th><th>{vb:rawphrase quiz_choices}</th><th>{vb:rawphrase quiz_score}</th></tr></thead>
<tfoot><tr><td colspan="4"><div id="paging"><input type="submit" value="{vb:rawphrase quiz_submit_question}"></div></td></tr></tfoot>
<tbody><tr>

is there any thing wrong?
