Double check the triggers.
The update is set to trigger when the button Submit is pressed:
// WA Application Builder Update
if (isset($_POST["submit"])) // Trigger
{
the first universal email behavior is set to trigger when the button test is pressed:
<?php
if ((isset($_POST["test_x"]))) {
//WA Universal Email object="mail"
the second is set to trigger when the button reset is pressed:
<?php
if ((isset($_POST["reset"]))) {
//WA Universal Email object="mail"
try setting the UE behaviors to use the same trigger as the update behavior, button submit pressed.
