Save Last Layer Config

Greetings!

I have created a fillable form for my company. I have radio buttons that toggle on and off layers and interactive fields depending on what marketing piece the person wants to request.  If the person selects the "Flyer" radio dial, the form shows the only the layer and fields for Flyer-specific questions.

It works great but for one issue: It does not save the last layer configuration after the form is saved and closed.  It does save the filled-in fields. The form default is to not have any questions showing (forcing the form-filler to select a radio dial).  But after the form is filled out AND saved, I want to the form to open on the layer that was saved. It currently reverts back to it's default blank state.

I am a novice (literally brand new) to the world of Javascript.  Does anyone have a javascript code to fix my issue? Something I can copy and paste? Also, please specify HOW/WHERE to place the script in the document or attach it. I've tried other solutions on this forum, but they didn't work. I don't know if coded the lines correctly.

I have attached the form below.  Thank you in advance for your time!
