My onClick Button Function does not pull Input Field Value into Text Field

Hello everyone, I am making a form that opens sections that need filled out and closes sections filled out. I am trying to display the Input values into text on the closed sections. The best way i’ve found to do this is with a button and onClick Function. Since onKeyUp or OnChange does not get triggered by autofill on chrome and some other browsers. But the problem is the Values are not being copied over. Any suggestions? Please Help!
And here is published site form so you can see it not working.

Try and resolve the console errors for your site. That’s probably what’s causing the issue.

Thank you for replying I will look into the console errors. This is my first site.
