How to enable Autofill on the form

I have this test form I'm playing with: http://form.jotform.ca/form/60885639075266.

I need the form to "remember" the selection for the subsequent submissions.

I'm trying to pre-populate the form from the thank you page using the field variables like this:

It's not working and I'm not sure how to pass the value to the form on next load.

Is this possible?

btw, the form is embedded.

If you only need it to "remember" the previous answers on the same form, then you can just enable Autofill feature.

Let us know if this is not what you need.

Thanks.
