Can't Reference A Custom Control On a Custom Form

[David M.]

Does anyone know why I can't reference a custom control
(combo box) on a custom form?

I use the following:
Set FormPage = Item.GetInspector.ModfiedFormPages
("Newform") [Works OK]

Set ControlX = FormPage.Controls("cboRequester")
[DOES NOT WORK. CODE STOPS AT THIS POINT]

I am using Windows 2000 (as a non-ADMIN user) and
Outlook 2000.

All help is appreciated.
