Я так и не пойму, в каком фале что исправить, или куда правильно добавить. Прошу Вашей помощи.

В своем сообщении не указал версию. 7-ка.
Вопрос по реализации этого предложения:
Предлагаю иной вариант, который я у себя реализовал.
Я просто спрятал кнопку "оформить заказ" и вывел сообщение о, том что сумма заказа менее минимальной.
Находим в шаблоне корзины:

<div class="gray_button">
        <div>
             <input name="step_1" value="Оформить заказ" type="submit" style="font-weight: bold"/>
        </div>
</div>


и преобразовываем его до состояния:


<xsl:if test="total_sum_without_discount &lt; 200">
    <p><h2>Заказ не может быть обработан, так как сумма вашего заказа менее 200р. </h2></p>
</xsl:if>

<xsl:if test="total_sum_without_discount &gt; 200">
    <div class="gray_button">
   <div>
   <input name="step_1" value="Оформить заказ" type="submit" style="font-weight: bold"/>
   </div>
    </div>
</xsl:if>

Получается что при сумме заказа без скидки менее 200 рублей выводится надпись "Заказ не может быть обработан, так как сумма вашего заказа менее 200р.", а если сумма заказа больше то выводится кнопка "Оформить заказ".

а чем ваш вариант отличается от https://www.hostcms.ru/forums/22/4139/#38025
