Couldn't save data

[bluetoothbj]

Dear sir:
I created two lists and made data joins. But I it couldn't save data. (No records in lists)

ERRor
"Notice :
Please enter a username.
VALID_AZ09"

Does someone know what is the problem?
(Or if you need more information)
Thanks!

This looks like a validatioin error. Do you have added the juser form plugin to your form?

Beside of this: in Fabrik one "leg" of a join must be an internal id (primary key), you can't join field to field.
