set focus

How do you set the focus to a control in vbScript?
My code here doesn't seem to like the line TheForm.InHouse.SetFocus

Code:

---

<SCRIPT LANGUAGE="VBSCRIPT">
<!-- hide script from older browsers
Sub cmdSubmit_OnClick
        Dim TheForm
        Set TheForm = Document.forms("frmSubmit")       

        If TheForm.InHouse.Value = "" Then
                MsgBox "Please enter a value for In House", 0, "Census Report"
                TheForm.InHouse.SetFocus
        Else
                TheForm.Submit
        End If
End Sub
-->
</SCRIPT>

---

Never mind, I found it. It should have been
TheForm.InHouse.Focus()

This and other little differences between VB and vbScript have been driving me apesh!+. Does anyone know where I can find a good outline of the differences between the two?
