Question - How do I take some meal money off one student and put it on their sibling?
Answer - First go to Admin>Meals>Student Meal Payments and find the student you want to take the money off.
If former year 6 students, choose Year 7 and Former students.
In the pay column type the amount as a minus, for example, -10 and click the pay icon.
Now go to the sibling and make a normal payment of the amount you took off the other student, for example 10 then click the pay icon.
