    Calculate the total value and pass it to the payment field

    Asked by IOH on September 10, 2015 at 10:41 PM

    I want to create a form for users to pay invoices by Credit Card online.

    What I want is the user to have a list they can add to with two columns: Invoice Number, Amount, with the amounts then totalling to a total row and being able to have this amount populate into the payment amount of payment widget.

    Is there a widget like this?

    Yes, that's possible.

    Basically, you have to add fields on your form then perform calculation using the form calculation widget. Guide: http://www.jotform.com/help/259-How-to-perform-calculation-in-the-form

    After that, you can pass the total value on the calculation widget to the payment field as the payment amount. http://www.jotform.com/help/275-How-to-pass-a-calculation-to-a-payment-field

    If we can be of further help, please let us know.
