    Can the form do calculations in certain increments?

    Asked by Daphne K.  on August 19, 2014 at 10:46 AM

    I have a form (using PayPal Pro as my payment module) where it calculates the total amount based on number of hours.

    For example, if I am creating a form where the rate is $55/hour, and someone wants to purchase 3.75 hours. So upon submission, the info that should go to PayPal is that $206.25 for that 3.75 hours.

    3.75 x $55.00 = $206.25

    Can JotForm handle calculations in such increments (0.25, 0.50, 0.75)? I did a test, and it looks it's only doing the calculations based on whole numbers. Hopefully the attached screenshot will help.

    Hopefully this question makes sense.

    Yes, you could make something using a custom calculation widget and then pass the value to your payment field:


    Here is a small demo form I made to show you what I am talking about:
