    How to add formula for calculation within form?

    Asked by jlmiller2 on September 05, 2013 at 01:04 PM

    For example, I am creating a nutrition log - capturing calories consumed, calories burned.  Would like to add an auto fill whereas the total is automatically calculated.

    Hello Jlmiller2,

    Calculation feature is not available in JotForm, however it's still possible to do the calculation by adding custom code in your form. To do this you will have to download your form's full source code and then add the custom code.

    Here is a guide to help you download your form's source code:  http://www.jotform.com/help/104-How-to-get-your-Form-Source-Code

    Do let me know and I can create a demo form for you.

    Thank you!
