How can I have a "Submit" button before presenting survey calculation results?

I have a form that collects information, performs some calculations & then presents a summary of findings based on the calculations.

The problem is that anyone can fill in the questions, then see the results (which are displayed in a Text section) before they need to hit submit.

What I really need is to be able to have the Submit button after the questions have been. asked, then present the results pages (there are multiple based on the previous answers).   That way, we do get their contact details in the system.

I'm afraid that's not possible with Review Before Submit feature. Preview will always come first before the submit button.

The workaround is to disable Review Before Submit then enable  POST Data in your form so you can capture the form's data after the form is submitted and show it in your custom thank you page. Your custom thank you page will serve as your review page. This would require programming knowledge like PHP to achieve this. You will find this guide helpful about showing the post data on thank you page http://www.jotform.me/help/213-Send-POST-Data-From-JotForm-Using-PHP-in-Custom-Thank-You-Page
