newbie question about Total Number of Students

[Bob Ahrens]

What does the Total Number of Students parameter do on an Activity?  How does it work with the number of students assigned to a Group of Students in a StudentSet? If the number of students assigned to a Group of Students in a StudentSet >  Total Number of Students parameter on an Activity, what happens? 

[Liviu Lalescu]

Each students set has a certain number of students.

Each activity has by default the number of students equal with the sum of the number of students of each students set that it involves. In this case, when adding an activity, leave the number of students = -1 (automatically computed), and in the .fet XML file do not add the Number_Of_Students field.

If you want to override this with an exact number specified by you, just specify the Number_Of_Students or set this value in the spin box when adding an activity.

This facility (to override the computed number of students) was requested by some users a long time ago.
