having NOCHEX trouble sending correct order totals

Recommended Posts

Hi... I am using a pretty old snapshot of osC(TEP) but I have been modding it up here and there over the years (yup, it's a version from 2002!) and it works a TREAT. Although heavily customised, nothing from the actual functions, classes or modules have been tampered with. I recently switched from WorldPay to NOCHEX for my payment handling and just found an error with this contribution (the only one that actually works until reaching the NOCHEX server):




the order totals that go to the NOCHEX server always report as only ?7 (my delivery charge) rather than including the order total, delivery charge and tax (VAT) all together!


Here is the code for nochex.php from my catalog/includes/modules/payment

   function keys() {

     return $keys;


this is the line I have been trying o tamper with to get the right results but anything I try either makes no difference or just changes the amount forwarded to NOCHEX's servers to ?0.00:


                               tep_draw_hidden_field('amount', number_format(($total_cost + $total_tax + $shipping_cost) * $currencies->currencies['GBP']['value'], 2)) .


any help any one?
