Как узнать сумму значений в переменной?

Secret73:

{$i = 0}
{foreach $order_data.items as $n=>$item}
      <tr class="tr">
        <td class="td">{$item.cartitem.amount}</td>
{$i += $item.cartitem.amount}
      </tr>
    {/foreach}
{print_r($i)} // Это и будет сумма вашего столбца

Как узнать сумму значений в переменной?

или Вам сумму элементов всех, которые лежат в этих переменных?
