How to Requery a combobox of a subform inside a main form?

Question

I'm a beginner in MS Access and this is my problem;).

• Home is the name of the mainform
• levisite is the name of the subform
• CasellaCombinata0 is the name of the combobox.

Here is the code (VBA) associated to an event on a click on the combobox where I call the query named LastVisit :

Private Sub CasellaCombinata0_Click()
   Dim Variable1 As Date
   Variable1 = DLookup("reservationdate", "LastVisit")
   Me.DisSelected.Caption = "The last visit was: " & Variable1
End Sub

Here is the code (sql) of the query "LastVisit":

SELECT Max(reservation_date) AS reservationdate
FROM Appointment
WHERE (((Appointment.ID_SP) = TempVars!TempID) 
  And ((Appointment.ID_patient) = Forms![levisite].[CasellaCombinata0]));

I don't know if the last notation is correct: Forms.[levisite].[CasellaCombinata0] . I get this error:

Run-time error "2450" Application cannot find form '"levisite".

But when I run it directly to the subform it works and I don't know where is the problem. Thanks for the attention!

Answer 1

The right answer is the following notation:

Forms.NavigationBar.Subcontrolname.Form.Comboxname

So in my case it was:

Forms.Home.SottomascheraSpostamento.Form.CasellaCombinata0

The subcontrol is not the name of the subform but it's where the subform resides.
