Can I Change Layout Names?
Yes. There are no layout names hard coded into the calendar.
Can I change table occurrence names.
You should not change the name of our CalendarInterface or CalendarRows table occurrence, but you can change the name of "SampleEvents". When you do, be sure to edit the first Set Variable in the script "Load Source's FileMaker Fields --- Edit which Tables to use here ---" to teach it about the new name of your table occurrence.
