@sapirh Could not see the forest for the trees. Had been so focused on coding this that missed simplest manner to handle my situation. Since my system set up where user is already in the database, just used datasets to connect a dropdown to their email and use that as form input.
But could use a nudge on how to implement a hide/show button for user. Want to limit access to this page if they have already completed this new input. They can input a personal profile, and a business profile to the database. So already have a function that checks and limits access via their email count so only one personal profile can be set up. So to limit for this business I want to hide/show the button for access to this new creation by querying the type (a field in database)…so if type is business, then they can not see button.
