Thanks for the response and invitation to look at the appointments.
I would love to show you screenshots BUT I have no idea how to get them to you. I have no idea how to respond to you either as there is no reply button or any way for me to attach an answer.
This is the calendar:
How do I show you that I used the Appointments+ calendar to select the dates for Dec (23 to end of Dec) and for the first two weeks in January. I just clicked on the dates and they were added (with a comma between) to the line of excluded dates.
It should be simple but it isn't.
