Anna:
Looking at your the Failure message, it seems that you didn't add a
schedule date. Did you add a date before submitting the form? If not,
try doing that and see if you get the error. The only way I can
reproduce your Failure message is if I forget to add a date before
submitting.
One thing I'm working on now is improving the form interface for
adding dates, to make it a bit more intiutive. Currently, you either
have to pick a date from the calendar, or enter it directly using YYYY-
MM-DD format (so 2009-08-24). Then, you have to enter start and end
times using 24-hour time. For the next release I'm going to change the
way users enter start and end times. If you have suggestions for this,
do let me know.
