SUMMARY
=======

In Microsoft Word, there is no built-in functionality to force a user to select
only one Check Box Form Field out of a group of check boxes.

For example, if you have three check boxes: Yes, No, and Undecided, the user can
select more than one at a time. However, you want to limit the user to selecting
only one check box.

This article describes a method using Visual Basic for Applications that you can
use to force a user to select only one check box from a group of check boxes.

The following sample Visual Basic for Applications macro demonstrates two groups
of check boxes on a form. One group contains check boxes named Yes, No, and
Undecided and the other group contains check boxes named True and False. When
you select one of the check boxes in the group, the other check boxes are
cleared.

     Sub ToggleCheckBoxOnEntry()
        Dim fFields As FormFields
        Dim fSelectedField As FormField
        Set fFields = ActiveDocument.FormFields
        For Each fSelectedField In Selection.FormFields
           ' Form field must be a check box.
           If fSelectedField.Type = wdFieldFormCheckBox Then
              ' Go to the case for the currently selected group.
              Select Case fSelectedField.Name
                 ' Yes, No, or Undecided check box group.
                 Case "Yes", "No", "Undecided"
                    ' Clear all values.
                    fFields("Yes").CheckBox.Value = False
                    fFields("No").CheckBox.Value = False
                    fFields("Undecided").CheckBox.Value = False
                 ' True or False check box group.
                 Case "True", "False"
                    ' Clear all values.
                    fFields("True").CheckBox.Value = False
                    fFields("False").CheckBox.Value = False
                 ' You can add other Case statements for other groupings.
                 ' For example:
                 'Case
                 '   <Code>
                 'Case
                 '   <Code>
                 Case Else
              End Select
              ' Check the selected formfield.
              fSelectedField.CheckBox.Value = True
           End If
        Next
     End Sub

To use this macro for any check box grouping within your document, assign
ToggleCheckBoxOnEntry() as the Entry macro for every Check Box Form Field in the
group.
