Forms can now ask which children a form is about.
A parent filling out a form sees a checklist of their own children and ticks the ones it applies to, so a permission slip can cover two children out of three, or a survey can go to just the oldest. You can then download the results as a list of students with their grade and homeroom, instead of a list of parent names. When the form collects a payment, the amount follows the number of children chosen. Because it draws on a parent's own children, this field can only be used on forms sent to parents.
Each child can only be signed up once per form. If two guardians of the same child submit at the same moment, the second one sees a clear message naming the child and the guardian who already signed them up. If a payment is later reversed by a parent's bank, that child stays on your roster and stays registered to the family who signed them up, so you can see there is a payment to sort out rather than quietly losing the child from your list.
