OK, I see now. The reason your menu selections are blank is because you need to create a phrase with var name two_weeks (it should be of type Calendar).

The other thing is that in file includes/functions_calendar.php there's an array of allowed reminder values, so you'd have to add your two week value to that. If you'd rather do it via plugin I think you can create one using hook calendar_start and code like:

$reminders[1209600] = 'two_weeks';

Edit...ah, this still might not work. I'm still looking at it...

Edit: OK, I got the above code wrong. Should be OK now.
