Additional steps on the order form?

ii) Can there be an intermediate step added in the following fashion:

   - user fills in the form 
  - user clicks "next"

   - user sees what he/she ordered - and clicks "Confirm" - only then the form is submitted... 

You can do this by making the form multipage, here's a guide that you can follow: http://www.jotform.com/help/119-How-to-Create-Multi-Page-Forms 

After that, you can then add the "Preview Before Submit" widget, here's the widget page: http://widgets.jotform.com/widget/preview_before_submit. To add a widget, you can follow this guide: http://www.jotform.com/help/252-How-to-Add-a-Widget-to-your-Form 

That widget will allow your users to preview the answers or the order before submitting it.

I hope that helps.
