I have developed a form with fields hidden by default, that become visible based on box ticked or radio button selections.

My problem is that, when I close the form and re-open it, it comes back to it's default presentation, regardless of the information already recorded in the form (including in the now hidden fields.

How to correct that

Thanks in advance for any hint you can provide.
