For more information about how to use the sample code in this article, click the article number below to view the article in the Microsoft Knowledge Base: The following sample Visual Basic for Applications macro demonstrates two groups of check boxes on a form. One group contains check boxes whose bookmark names are Yes, No, and Undecided, and the other group contains check boxes whose bookmark names are True and False. When you select one of the check boxes in a group, the other check boxes in that group 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. To assign the macro to the Run on entry, follow these steps:

1. Double-click the form field that you want to add the macro to. This displays the Check Box Form Field Options dialog box.
2. Under Run macro on, click to select the Entry list. Click to select ToggleCheckBoxOnEntry from the list of macros, and then click OK.
3. Repeat these steps for each of the check box fields.
4. Protect the document by clicking the Lock button on the Forms toolbar. Or, on the Tools menu, click Protect Document, click to select Forms and then click OK.
