How to save a form before submitting?

How do we add the capability for a user to save their progress on completing a form, and come back and edit from the place they left off? 

There are two different ways to save the form before submitting. 

1) You can do that by saving input data in the session. In this case, you should have the session ID, so data can be accessed from anywhere. 

2) Next way of doing that is to enable the "Auto fill" feature of your form. In that situation, your input data will be saved in your browser cookie. Note that data will be available from that browser only.

Here is the related guide.

Thank you for the quick response. We’ve followed the first guide and
implemented this, but when we exit the form and return, it takes us back to
the starting point, rather than picking up from where we left off. How do
we fix it so that someone can save their progress, and return to where they
left off on the form?

Hi, I’ve corrected this, but the same issue persists. I don’t see a way to
SAVE the progress of the form.
When I go to the email that is sent and click the link, it just takes me
back to the start of the form. ☹

OK, I checked your form and can see that the link on your thank you page is still incorrect, its missing the equals sign.

However, you autoresponder email is correct. So emails should be working now.

Ahh, thank you so much! I had updated the email, but not the thank you
page. It is working now!!!!
