Capture input from page 1 of form and automatically populate it in page 2 of form

Is it possible to capture input from a text field (FirstName, LastName) on a form on page 1, and automatically populate it in a section of page 2 of the same registration form?

For example, on the first page, I want the Boat Captain to enter his name, then click Next. On the 2nd page I want him to enter his fisherman's names, but have his name populated and not able to be changed when he gets to this page.

Hello,

Yes, this is possible. By using the Update/Calculate field condition you can update a field such as a name to update upon key input of the 1st field.

Here's an example:

On my form I have two name fields. One indiciated as (2. Name), and the 2nd field indicated on conditions as (4. Name). 

Set your rule that if it is filled, copy the field's value to the next name field. Please check the screenshot below:

Once done, save your condition and it should update and copy the 2nd name field from the 1st name field. Then the user can also edit the 2nd name field without problems.

If you have questions, please let us know.
