Comparing 2 list of things and showing in RC

Hi, I have a db type called “Horario Negocio”. In there we have two list of things: “Fecha Reserva” as a list of dates and “Reserva Owner” as a list of text. We want to show in a RC all “Fecha Reserva” that match with “Reserva Owner” when “Reserva Owner” is the Current User’s email.

Thanks in advace. I am really stuck with this.
