I'm looking for an extended 'CHOICE' activity that does the following:
Students need to make choices for several activities. Every activity is a certain amount of hours (between 3 and 7). Students must register for a minimum of 14 hours activities, but a maximum of 25 hours of activities.
We need to make sure a student doesn't register for to little or to much hours.
Also: we want limitations on the number of students per activity. At least 5 students should register for an activity for it to even start. A maximum of 20 students per activity can be registered.
The choice module does have a maximum, but not a minimum registrations.
Are there custom plugins out there to set something like this up?
