Auto submission

I am not sure if I understood coorectly what you are looking for.

We do have a Widget that adds a countdown timer on your form. The counter prevents the form from being submitted, or submits the form right away as soon as the time has run out. You can select which of these two events to perform in the widget settings.

Please take a look at the  Global Timer Widget  link to find how to use it: http://widgets.jotform.com/widget/global_countdown.

I hope this helps. If any other question please feel free to contact us.
