Refer to named SpinButton in VBA

I have a SpinButton in my Excel worksheet (not on a form), that I have named "spinMonth". I have assigned a VBA macro called "spinMonthClick" to the SpinButton. In the macro I want to refer to the Value property of the SpinButton. How do I do that? I can refer to the SpinButton as a Shape using ActiveSheet.Shapes("spinMonth"), but this doesn't give me access to the Value property.

Thanks in advance.
