Freeshipper zip code array failed - allowed an ineligible zip.

[amylynpace]

$free_ship_postcodes = array('53044','53081','53085','53083');

That's the line in my modified freeshipper module that is supposed to allow free shipping to only those zip codes.

Yesterday, we received an order from 53058 with free shipping selected. I tested it and sure enough, it worked.

I am not a code writer and only modified the freeshipper code by changing this array. Is my syntax bad?

Here it is in context:

 		 // check to see if postal code is in list of allowed codes:
      } else {
        $free_ship_postcodes = array('53044','53081','53085','53083');
        $customer_postcode = $order->delivery['postcode'];
        $check5digitcode = substr($customer_postcode, 0, 5);
        $valid_digits = in_array($check5digitcode, $free_ship_postcodes);
        if ($valid_digits) $this->enabled = true;

      }

Thank you in advance for helping me out with any ideas you might have.
