There is no code in your attachment. From your description you should have:
Code:
Private Sub Document_ContentControlOnExit(ByVal CCtrl As ContentControl, Cancel As Boolean)
With CCtrl
Select Case .Title
Case "Checkbox1"
ActiveDocument.SelectContentControlsByTitle("ConditionalText1")(1).Range.Font.Hidden = Not .Checked
Case "Checkbox2"
ActiveDocument.SelectContentControlsByTitle("ConditionalText2")(1).Range.Font.Hidden = Not .Checked
End Select
End With
End Sub
Additionally, I can find no checkbox titled 'Checkbox2'.
Furthermore, I note your conditional texts include tables. Hiding the text in those content controls cannot hide the tables. Accordingly, you need a different approach - one that uses field coding to conditionally display the content or that conditionally inserts Custom Quick Parts into the document from its template.
