this line of code is not correct:
if ($_POST['callbackPW'] == "removed" && $_POST[transStatus] == "Y") // Trigger
it should be:
if ($_POST['callbackPW'] == "removed" && $_POST['transStatus'] == "Y") // Trigger
notice the difference in referring to the transStatus post element:
$_POST['transStatus']
instead of:
$_POST[transStatus]
