The simplest way is to use a ContentControlOnExit macro, coded along the lines of:
Code:
Private Sub Document_ContentControlOnExit(ByVal CCtrl As ContentControl, Cancel As Boolean)
Dim StrOut As String
With CCtrl
If .Title = "CC1" Then
If .Range.Text = "meets" Then
StrOut = "0.25"
Else
StrOut = ""
End If
ActiveDocument.SelectContentControlsByTitle("CC2")(1).Range.Text = StrOut
End If
End With
End Sub
