Confirm.php - button Modify Information

I have used eCart Checkout Wizard for creation of all checkout pages.
Subsequently, I changed the form on page checkout.php with help of CSS Form Builder.

I have noticed that when I on page confirm.php click the button "Modify information", the form on which I am returned to is empty.
I suppose that allredy entered data should stay?

How can I solve the problem?

on the checkout page select each form element.

on the properties panel, click the lightning bolt icon next to initial value.

From the Bindings panel, expand the Validated Entries collection, select the corresponding validated entry. When prompted for a default value, click the lightning bolt again, this time expand the session collection. select the eCartCheckoutForm_<element Name> session variable where <element Name> is the name of the form element you are binding.

I did as you described, at least I think so, but the matter is still not working.
In bindings panel, in the Validated Entries collection and also in the Session collection, I do not see fields which I have added with CSS FormBuilder and still see the fields which I have removed with the same extension.

I am attaching my checkout page so you could see if I have do it right, what is wrong.

Thanks

the issue is that the form elements are being renamed, this means you will need to edit all of the set session value behaviors on the confirm page to recognize the new form element names.


on the confirm page, go to the bindings panel. click on the plus button and select form data. click the folder icon and select the checkout page. this will add dynamic data bindings to the confirm page for the form elements from the checkout page.


you then need to go through each of the set session value behaviors on the confirm page and bind the values to the appropriate form element from the checkout page.
