Hi,
You'll have to add the code:
$document = JFactory::getDocument();
$checkout_name = JText::_('CHECKOUT');
if (empty($checkout_name)) {
$checkout_name = $app->getCfg('sitename');
}
elseif ($app->getCfg('sitename_pagetitles', 0) == 1) {
$checkout_name = JText::sprintf('JPAGETITLE', $app->getCfg('sitename'), $checkout_name);
}
elseif ($app->getCfg('sitename_pagetitles', 0) == 2) {
$checkout_name = JText::sprintf('JPAGETITLE', $checkout_name, $app->getCfg('sitename'));
}
$document->setTitle( strip_tags($checkout_name) );
after the line:
$this->assignRef('display_checkout_bar',$this->display_checkout_bar);
