Some missing info: Are Region and Area the names of Outlook custom properties? Is Area a multi-select combo box since you' talking about it having multiple values? (Can't say that I've ever seen one)

Hi,

I wonder if you could help me. I am having difficulties with validating
fields in an Outlook 2003 form.

Region: 1l Area: a, b
Region: 2l Area: c, d
Region: 3l Area: e, f

In my form I have created a ComboBox called “Region” containing values 1, 2
and 3. The values in my next ComboBox called “Area” should be dependent on
the value selected in the first ComboBox “Region” e. g. if a user selected
Region “1”, in Area there should be values “a” and “b”, if a user selected
Region “2”, in Area there should be values “c” and “d” and so on…

I would be very grateful if you could help me

Thanks

Zuzana
