payment zone not work with alertpay

[fony]

hi guys,
I am using alertpay modules to accept payment,
for US customers, they can pay by alertpay and money order,
and for customers outside US,
only can pay by money order,
I created the zone including US only,
and configured the tax rates for it,
when I set this zone to alertpay,
but it not work.
always display alertpay payment option for all customers,
here is the alertpay source code I use:

thanks a lot...

i get it work...
something missing in the source codes,
some part of the source codes should be:

// class constructor
    function alertpay() {
      global $order;
      $this->code = 'alertpay';
      $this->title = MODULE_PAYMENT_ALERTPAY_TEXT_TITLE;
      $this->description = MODULE_PAYMENT_ALERTPAY_TEXT_DESCRIPTION;
      $this->sort_order = MODULE_PAYMENT_ALERTPAY_SORT_ORDER;
      $this->enabled = ((MODULE_PAYMENT_ALERTPAY_STATUS == 'True') ? true : false);

      if ((int)MODULE_PAYMENT_ALERTPAY_ORDER_STATUS_ID > 0) {
        $this->order_status = MODULE_PAYMENT_ALERTPAY_ORDER_STATUS_ID;
      }
      $this->form_action_url = 'https://www.alertpay.com/PayProcess.aspx';

      if (is_object($order)) $this->update_status();
    } 

add global $order; before $this->code = 'alertpay';
and add " if (is_object($order)) $this->update_status();"
after " $this->form_action_url = 'https://www.alertpay.com/PayProcess.aspx';"
that is all,
and it work,

Thanks for the update and for posting the solution on the missing global that was resulting in the issues ...
