In Microsoft Word, there is no built-in functionality to force a user toselect 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, theuser can select more than one at a time. However, you want to limit theuser to selecting only one check box.

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

One group contains check boxes named Yes,No, and Undecided and the other group contains check boxes named True andFalse. When you select one of the check boxes in the group, the other checkboxes 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, assignToggleCheckBoxOnEntry() as the Entry macro for every Check Box Form Fieldin the group.
