Hi
i made a split form with two not related forms:

the one in the left called "nav" is just to open other forms, the bigger one on the right is called "candidati" and the split main form is called "lista calendario"
in the right form "lista calendario" i used the C button to navigate to a form called "candidatiS1" that was a single form. Now i made a split form adding the same "Nav" form as you can see, and i gave the name "candidatis1" to the split form and the old "candidatis1" (the single form) now is called "candidati"

this is the code i used to navigate to the single form, now i'm not able to set the recordsource of the "candidati" form in the split form "CandidatiS1"
Code:
Private Sub Comando494_Click() If CurrentProject.AllForms("candidatis1").IsLoaded = True Then
Forms!candidatis1.RecordSource = "SELECT Candidati.* FROM Candidati WHERE (((Candidati.IDcandidato)= " & Me.Candidato & "));"
DoCmd.OpenForm "candidatis1", acNormal, , , acFormReadOnly, acWindowNormal
Else
DoCmd.OpenForm "candidatis1", acNormal, , , acFormReadOnly, acWindowNormal, Me.Candidato
End If
End Sub
