    Hello bheqman,

    Do you actually want to do some mathematical calculation in your form?

    It is not possible to do calculation with in JotForm editor. But it can be achieved by downloading your form's source code and add custom JavaScript code for your calculation operations.

    Please be noted that if you embed you form with your form's source code, any changes you make in your form editor will not reflect in your web page automatically. You will have to download the form's source code and merge the custom code again before embedding it in your webpage.

    If that is acceptable to you, do let us know your calculation formula and your form id in which you want to implement. We will help you with custom code.

    Thank you!
