No one?

I have now at least identified which part of the code that generates that small table of 4 rows (From "Summa" to "Totalsumma"), found in orders.php but it is (more or less) identical in invoice.php:

Code:
    for ($i = 0, $n = sizeof($order->totals); $i < $n; $i++) {
      echo '              <tr>' . "\n" .
           '                <td align="right" class="'. str_replace('_', '-', $order->totals[$i]['class']) . '-Text">' . $order->totals[$i]['title'] . '</td>' . "\n" .
           '                <td align="right" class="'. str_replace('_', '-', $order->totals[$i]['class']) . '-Amount">' . $order->totals[$i]['text'] . '</td>' . "\n" .
           '              </tr>' . "\n";
    }
I understand it gets the info from a 2x4 matrix called "order" or "totals" but I don't know enough php code to easily find out where the info is put into this matrix. I don't know what the symbol "->" means but I'm guessing it fetches the "totals" part of a structure called "order" perhaps. Anyway, searching through all php files for the phrases "totals" or "$order" gives too many hits. I could need some help..
