User defined Field in Custom Form

[fullyii]

I created a custom form in outlook 2007.

I can access the values of the standard Appointment

Dim oAppt As Outlook.AppointmentItem
.
stream.Write (oAppt.Categories) 'Category
stream.Write (oAppt.Subject) 'Subject
stream.Write (oAppt.Location) 'Location




I created a Custom form that includes:

• Appointment - Standard tab - I can get values from this tab as stated above
• Request demographics - new tab i created that contains 2 combobox controls
  • Combobox1 -
  • Combobox2

I need to know how to get the values of the user defined fields Combobox1 and Combobox2.

Thank you.
