Importing Training Plans

I think I've followed all steps correctly,

I've made a half-marathon training plan to import, using the CSV template provided in the readme.  For the plan, no mileage or time is set in stone, so the only thing entered is the number of the day (1, 2, 3...instead of dates), and the workouts are listed in the Overall Comments column.  This is the error I get when I try to upload said plan onto BT.  Any ideas?  I went back and looked and sport comments is not on the template, should I add it?  Thanks!
