Im looking for a landing page that only accepts people that have a code.
That code will have all the info related to that person.
After the code is entered they can edit their contact info and click save. Either way the form will be submitted.
Basically this is a form for people with a special invite.
If they do not have a special ID they can continue with an alternate page that will accept a larger amount of info to register a person but will not pull from a database.
