X-Cart forums - New side box title problem

Hello, I'm adding a new side box to the left bar of my site, but there is a problem with displaing the title of the box. Check the last 3 rows of my code:

PHP Code:


		
			
{*
$Id: menu_users_online.tpl,v 1.10 2008/10/29 16:50:56 max Exp $
vim: set ts=2 sw=2 sts=2 et:
*}
{capture name=menu}
{if $users_online}
  <div class="uo-box">
      <strong>{$lng.lbl_users_online}:</strong>&nbsp;
    {foreach from=$users_online item=v name="_users"}
        <span class="item nowrap">{$v.count}
        {if $v.usertype eq 'A' || ($v.usertype eq 'P' && $active_modules.Simple_Mode)}
          {$lng.lbl_admin_s}
        {elseif $v.usertype eq 'P'}
          {$lng.lbl_provider_s} 
        {elseif $v.usertype eq 'B'}
          {$lng.lbl_partner_s} 
        {elseif $v.usertype eq 'C' && $v.is_registered eq 'Y'}
          {$lng.lbl_registered_customer_s} 
        {elseif $v.usertype eq 'C' && $v.is_registered eq 'A'}
          {$lng.lbl_anonymous_customer_s}
        {elseif $v.usertype eq 'C' && $v.is_registered eq ''}
          {$lng.lbl_unregistered_customer_s} 
        {/if}
        {if not $smarty.foreach._users.last}, {/if}
      </span>
    {/foreach}
  </div>
{/if}
{/capture}
  {include file="customer/menu_dialog.tpl" title="{$lng.who_is_online}; " content=$smarty.capture.menu}

How to avoid getting an error and to display the title properly as a language variable?
