Form Submit Button is not showing up

I am not familiar with Jot Form. I don't know how to program the button to end the form. I don't know what the difference is between Next and Submit. I can't find where to add submit (to end the form) rather than next to continue. I am messing up the form :(

I see that you have already opened a separate thread regarding your concern.

I have already responded to that thread and may I suggest that you refer to it avoid confusion, please?
