Try this and see if it works. I set this up a quite some time ago. Sheet 1 = Mishnayos Herbst. sheet 2 = Mishnayos Extra. Use the extra tab if you want to learn Mishnayos for another person. Additional tabs may be entered as needed but please let me know when you do so. Please do not change the format of the spreadsheet.
