Lah-dee-dah ... it works
That change did it, Eric.
Can I give you a couple of suggestions that need to be dealt with?
1) Page three of your support document for Changing Payment Gateways (ps_change_pmtgateway_ecart.pdf) says (point #4) to "Leave the trigger option set to any form post". Does that need fixing?
2) Just a reminder that (as per your first response to this thread) any time the eWAY_XML_PHP.php gets altered it loses the $ symbols need for lines 113 and 114. That definitely needs to be fixed.
