On this page you have a list of courses (Course 1 to Course 6) and three
time periods (T1 to T3). The idea is that each person will select one
course for each of the three time periods.
I have it set up so that each time period has a set of radio buttons
associated with it (one for each course). This ensures that each person
can select only one course per time period. But it doesn't stop them
from selecting the same course for all three time periods - which I
don't want to allow.
Then there's course 6. Course 6 runs across all time periods. If you
select course 6 then you can't select any more courses.
rules. But I thought that the clever people in london.pm might have
some clever ideas. So I'm asking you first.
How would you implement this?
 And, yes, I know I'd need to implement the same checks server-side
