How to Create a "Start" and "Continue" Button?

Another difficulty that I encountered when I tried to create another Jotform is I don't know how to add a "Start" button and a "Continue" button. Please see attached.

Another thing, I don't know how to create a table that looks exactly like the one attached (3.jpg).

As far as I understand, you are referring to our save and continue option. We would like to suggest checking the following guide:
