Я нашел способ как вывести количество комментариев в шаблоне.
Просто вставить echo $count; прямо в функцию.

Но мне надо, что их количество выводилось внутри заголовка H4.
Но, когда я туда вставляю - ничего не выводится.
<h4 id="comments"><?php echo JText::_('COMMENTS_LIST_HEADER').' '.$count;?> <?php echo $btnRSS; ?><?php echo $btnRefresh; ?></h4>
Нужно как-то передать значение переменной из функции...
