Another solution:
I have created a button ho update the form
can i'm tryin to use the call enter comman but it give me error


this is my actual code is it possible to add the call command here?

Private Sub Comando12_Click()
On Error GoTo Err_Comando12_Click
DoCmd.DoMenuItem acFormBar, acRecordsMenu, 5, , acMenuVer70

Call filtro_unione_Enter

Exit_Comando12_Click:
Exit Sub
Err_Comando12_Click:
MsgBox Err.Description
Resume Exit_Comando12_Click

End Sub

(it does not filter when i open the form but a click on a mouse is not a problem

bye )
