Hello @asyoung3000 ,
What your code is currently doing is simply adding the registration form data into a collection. However, it’s not registering the user therefore when you prompt the default login, there is no “user” to be found in the .
I suggest taking a look at the documentation for the register() function this will register the user and they then can use the default login but their data will be stored in the privateMembersData collection which is read-only. So to bypass this and collect more information then what the privateMembersData collection allows, create a reference field inside MemberInformation collection and reference the user either by code or manually selecting the user. This way the member and your row of extra data are then tied together.
