Subform not displaying record

[raphael99]

Hi,
I have 3 tables:
tblAnagrafica
TabellaPIP
TabellaJoinPIP

By wizard I have build a form that collect data from a query: "QueryPIP2Tabelle"
The main Form :" frmtblAnagraficatest"
display correct data from tblAnagrafica,
BUT the subform: "frmTabellaPIP Sottomascheratest" does not display data from TabellaPIP.
Relations are many -to-many but, because it's my first building database, can be incorrect.
I post db, hoping someone give a reply. It's all the day I'm trying to work it outView attachment Database1.accdb

Did you link the subform to the main form?

I built it via wizard and I supposed it is automatic.
