I added Custom field “absent” for Student Attendance with Depends On
eval:doc.status=="Absent"

But when I create or create & submit New Student Attendance

I have absent field with first value “Absenteeism”.

But I need it null, because I don’t fill in it.

Please, help me.

I need set up custom field “absent” to null, when I create & submit New Student Attendance and choose Status “Present”
And set up “absent” to Absenteeism by Default, when I choose status “Attend.”
