Cerrar inputbox si no hay respuesta

I. Hola Toni, por mi parte no soy usuario habitual de VBA ni de Excel, pero como suelo comentar quisiera trasladarle la información que vi sobre su consulta por si pudiese serle de alguna utilidad mientras le atiende un experto o experta de primera mano, como Elsa Matilde o Dante Amor.

Le ruego me disculpe por todas molestias de tanta lectura y el tipo de respuesta. Ánimo.
