I am sorry you are unable to submit the registration form to the school district.
To help you further would you please share a screenshot of the error message you are receiving, while trying to fill out the Date of Birth field?
It keeps giving me an error message when I try to login to complete my daughters registration. It says there's a Snapcode error and that the snapcode is associated with blank account and I am entering that account but it still doesn't have her in that account. Don't know where to go from there. Please help!
