Hi @Erinedgestroud,
I am sorry you are facing issues logging in to the parent portal to register your kids. There may be an error with the access ID and password you were trying to log in with. I have attached an article here that should help walk you through this process.
If you are still unable to log in to the parent portal after the steps mentioned within the article, I recommend reaching out to the school district who should be able to assist you with logging in to the parent portal and enrolling your child in school.
