i have reproduced this issue with security assist and logged it in our system as a bug to be corrected in a future update.
to work around the problem, you will need to manually remove the bad code and reset the initial value for the radio buttons.
in the first button, delete this code:
php:
<?php if (array_search("1", ((isset($_GET["invalid"]) && ValidatedField("regme","Registration_group_Membership_Type"))?ValidatedField("regme","Registration_group_Membership_Type"):array())) !== false) {echo "checked=\"1\"";} ?>
in the second button, delete this code:
php:
<?php if (array_search("2", ((isset($_GET["invalid"]) && ValidatedField("regme","Registration_group_Membership_Type"))?ValidatedField("regme","Registration_group_Membership_Type"):array())) !== false) {echo "checked=\"1\"";} ?>
in design view, select the first radio button, in the property inspector, click the Dynamic button, click the lightning bolt icon next to select value equal to, in the bindings panel, expand the validated entries collection and select the Registration_group_Membership_Type radio group.
