Back to this problem. I have a WA update form in a iframe, the redirect is set in the wizard and does not offer a target as an option for teh redirectURL. I tried adding:
// WA Application Builder Update....
$WA_redirectURL = "http://xyz.com/123_pay.php target"parent"";
but it fails. So What I need to do is to click the update button aqnd have the redirect open in a new page.
