Thanks for your reply and very sorry to heard the situation that had happened at your place.
For your inform, i had found the way to do it.
But there's a another issue which i haven't figure out how to do it, that is how to insert the user profile field into the dataform?
As i see, there's indeed some default EAU --> Entry Author (internal) included.
If i want to add in another user profile field, for example: country, home address...etc
What can i do?
