    Can a sum be calculated by entering a number into a blank box?

    Asked by DanMyers on February 10, 2013 at 09:34 PM

    Im creating a residential estimate for my iPad. Lets say I have a box on my Jot Form for Square Footage. Is there a way to have that number calculate a price per square foot by a pre-entered formula?

    Hi,

    You can't do calculations of the text box fields directly to JotForm as of now. However, that's possible using your form source code and apply some javascript codes which may help create the calculation function. Can you provide to us the exact formula so we can help you do the coding?

    We'll await your reply. Thanks!
