Replace the code in the ThisDocument module with this
Code:
Private Sub Document_ContentControlOnExit(ByVal myCC As ContentControl, Cancel As Boolean)
Dim aCC As ContentControl, strSet As String
If myCC.Title = "EmploymentType" Then
strSet = myCC.Range.Text
For Each aCC In ActiveDocument.ContentControls
If aCC.Title <> "EmploymentType" Then
aCC.Range.Font.Hidden = aCC.Title <> strSet 'hide if CC title doesn't match selected employment type
End If
Next aCC
End If
ActiveWindow.View.ShowAll = False
ActiveWindow.View.ShowHiddenText = False
End Sub
