Run Tme Error 2147352567 (80020009) In MS-Access 2007

Gents,

I have created a timewrite program in Access. It worked ok in 2002 but now i'm getting the error:

Getting a runtime error 2147352567 (80020009)

Pointing to the code:

Code:

---

Private Sub Form_Load()

Me.objKalender = Date
Me.cboMaand = 0

End Sub

Private Sub objKalender_Enter()

Me.txtDatumSelectie = Me.objKalender.Value
Me.SF_Urenregistratie.Requery

Me.txtTotaalDag.Requery

End Sub

---

Tony, I'm not sure what some of the objects you've used in the code are. So one could comment if you attach the MS-Access file.
