Hello

I have the following situation:

The users can book training lessons. One lesson last one hour. Lessons are attached to Courses.

Course 1 is on August 8th and has the following lessons:
10:00 to 11:00 (= 1 lesson)
11:00 to 12:00 (= 1 lesson)

Course 2 is on August 10th and has the following lessons:
10:00 to 11:00 (= 1 lesson)
11:00 to 12:00 (= 1 lesson)

Course 3 is on August 12th and has the following lessons:
10:00 to 11:00 (= 1 lesson)
11:00 to 12:00 (= 1 lesson)

Users must book 2 lessons in minimum and it is not allowed to book these 2 lessons from the same course.
So, a person must book the first lesson from Course 1, 2 or 3. If booked from Course 1, the second lesson must be booked from course 2 or 3, but not from 1. But it can be course 2 and/or 3.

Is this possible with JEvents?

Thank you very much.

Regards
Patrick
