Copy fields within the same Appointment that has custom form

[bearsgone2]

I have an appointment that has a custom form attached to it called Transportation Form or P.2.

When a user is in custom form or P.2, upon cliking macro shortcut, some data fields will come over to first tab which is a regular appointment with subject, date and etc.

Not sure how to copy between different tabs within the same appointment. I get an error -2147024809?
Error is on Set ctrl = Application.ActiveInspector.........
Any help would be greatly appreciated!

here is my code:

Sub FormtoAppt()
Dim Subject As String
Dim objAppointment As AppointmentItem
Set myFolder = Session.GetDefaultFolder(olFolderCalendar)
Set myItem = myFolder.Items.Add("IPM.Appointment.Formv1")
Dim objAppt As AppointmentItem
Dim ctrl As Object
Dim ctrl2 As Object
On Error GoTo ErrorCode

If Application.ActiveInspector.CurrentItem.Class = olAppointment Then

Set objAppointment = Application.ActiveInspector.CurrentItem
Set ctrl = Application.ActiveInspector.ModifiedFormPages("Transportation Form").Controls("DestinationandAddr")
Set ctrl2 = Application.ActiveInspector.ModifiedFormPages("Appointment").Controls("objAppt.Body")
ctrl2 = ctrl

Else
MsgBox Prompt:="Please open Appointment"
End If

Exit Sub
ErrorCode:
If Err.Number = 91 Then
MsgBox Prompt:="Appointment must be open"
Else
MsgBox Prompt:="Gen Error!"
End If
End Sub
