Comment 2 for bug 1301885

OK, you had a few repeated lines in the first couple sections in SectionTimetables, and I got rid of those (attached).

I then got this:

is not a valid period id for the given day:
B10-12, B15-17, B21-23, B26-29, B33, B43-46, B49-51, B54-57, B60-62, B66

Which is caused by the period times corresponding to the times in the other timetable, so you'll have to sort that out manually.

Let me know if it works after you get those sorted.
