    I have a variable # of participants (2-6) with a known $ per participant ($92.25). Need to calculate total for charge for event + (participant charge * # of participants) + optional donations.

     

    I can currently do this, by asking # of participants within the payment section. I need to pull the # of participants from a field already completed by the user in the same form. This way they can't register a different number than they pay.

    What I currently have:

    I need to use a field previously filled in the same form. The field is a dropdown field with a 2 thru 6 value option.

    This value would used instead of asking the "Please enter the number of participants" (above) again to ensure the user is paying for the right number of participants.

    When i try to use a conditional entry, I don't see an option within the dropdown for the "Participant" field.

    You will need to use the User Defined Amount as the payment type of your form to achieve your requirement. This will require us to setup the payment options using the regular fields instead of using the payment field. We will simply pass the total amount calculated from the regular fields into the Payment Field. Please follow the steps below:

    1. Add a donation field using textbox

    2. Add a Form Calculation widget on your form. 

    3. Now setup the formula on the calculation field. You can follow this guide on How to Perform Calculation in the Form?

    I set the formula below as 107 + (92.25 * how many girls will be in the room) + Donation

    4. Now all we need to do is to pass the Total Amount calculated into the Paypal Payment field. Please follow this guide on How to Pass a Calculation to a Payment Field

     

    Save the setting and you're all set. You can check out my demo form here to see it in action: https://form.jotform.com/63248310703953  You can also clone it to your account to see my setup.

    If you need further assistance, please do let us know.
    Regards.
