Accordions State Changes


I am working on a checkout accordion in which the user can enter in their account and billing information, each in separate accordions. I would like them to be able to edit those once they initial fill them in. Example flow
The Account and Business Information Accordion is open by default OnPageLoad. User fills out form and clicks Continue. That closes the accordion, creates a summary view and should open the Billing Information accordion directly underneath the Account one. It is not doing that and and I am not sure how to get that to work? I am attaching my file for reference.
