It all has to get crammed into one macro - you can't have the same macro name in the same module.
Code:
Private Sub Document_ContentControlOnExit(ByVal aCC As ContentControl, Cancel As Boolean)
Select Case aCC.Title
Case "Awaiting Response", "Response Received"
If aCC.Checked = True Then
aCC.Range.Paragraphs(1).Range.Font.ColorIndex = wdRed
Else
aCC.Range.Paragraphs(1).Range.Font.ColorIndex = wdGreen
End If
End Select
End Sub
