Obrigado

**Charlie**You can perform form calculation by following this guide: http://www.jotform.com/help/259-How-to-perform-calculation-in-the-form.

You can calculate the difference of your time fields there. Or you can also use the time range option.

In the properties window, enable it also.

You can then use the Form Calculation widget to get the time difference.

Let us know if you need more information on this.

Thank you.
