    How do I make a price per unit fill in the blank?

    Asked by Wthomson on April 29, 2016 at 05:31 PM

    I want to allow users to fill in the price with a suggested minimum.  I'd like a minimum, but from what I've read, that is not an option.  We are doing multiple quantities, but would like them to donate more than suggested if they'd like.

    You can use calculation values:


    And total everything up in a calculation field:


    Then send that total to your payment field:


    Create a radio button field with the values you'd like to present and assign those calculation values.  Then, add a number field to the form for custom amounts.  Add those up in the calculation widget and use that total to your payment field.
