That was interesting. I did not see any problem using the folder icon, but the landing page has to exist to do that.
I tried creating one with the page not existing yet, but entering a relative link (../test.php) rather than a site root link. It appears to have generated most of the code correctly except the value of the fields.
The value of the fields came out as:
<?php echo((isset($_GET["invalid"])?ValidatedField("","Appointment_request_group_Best_day"):"")); ?>
which I believe should have been:
<?php echo((isset($_GET["invalid"])?ValidatedField("test","Appointment_request_group_Best_day"):"")); ?>
but the error message conditions look correct as:
<?php
if (ValidatedField('test','test')) {
if ((strpos((",".ValidatedField("test","test").","), "," . "5" . ",") !== false || "5" == "")) {
if (!(false)) {
?>
