I created my form following the on-line users guide.  That seemed to go okay.  It did not insert a submit button on my form like it shows in the tutorial.

You can add a submit button to you form. Here's how:

Open your form and go to the Basic Fields. Select the Submit Button field and drag it to your form.

Hope that helps. Let us know if you have any questions. Thank you.
