Activate only 1 combo box

Hello,

     In Excel 97, I have a form that has 3 comboboxes.  I'd like the user to be able to choose only ONE of the combo boxes.  (I have 3 combo boxes for 3 different categories, and only 1 of those can be processed).  

     For example, if the user chose a selection in combobox 1, but then also tried to select something in combobox 2, combobox 1 would be DESELECTED, and the new choise (combobox2) is the new selection.

     Does anyone have the work around for this?  
   Thank you!!!

The first item of the combobox reads something like "Select from list."  Then, with this code, if a selection is made in any of the combos, the others will reset to index 0 (top of list).

Private Sub Combo1_Click()
    If Combo1.ListIndex <> 0 Then
        'Reset all other combos
        Combo2.ListIndex = 0
        Combo3.ListIndex = 0
    End If
End Sub

Private Sub Combo2_Click()
    If Combo2.ListIndex <> 0 Then
        'Reset all other combos
        Combo1.ListIndex = 0
        Combo3.ListIndex = 0
    End If
End Sub

Private Sub Combo3_Click()
    If Combo3.ListIndex <> 0 Then
        'Reset all other combos
        Combo1.ListIndex = 0
        Combo2.ListIndex = 0
    End If
End Sub

I never did VBA but here is a thought. Create a Control Array and depnding on the ComboBox selected disable the other 2.

Erik37,

    Great...thanks so much for helping me with these combo boxes.  I really appreciate it.  I want to award you more points for such a great solution, but bumping it up to 25 is all I could afford right now.  

Thank you!
