Show a form's running total costs?

REGISTRATION FORM

Ringers is a wrestling school in Wisconsin. The primary need of the school is for wrestler registration forms for specific programs offered by the school during various times of the year. Our needs are unique. For example, we have programs that run for a term, say 3 months, that kids have the option of paying for the entire duration or paying for specific days.

In addition, kids have the option of paying daily. Which I imagine could be a specific registration form called "Daily Registration".

I did notice there was a wrestling registration form example that could accomplish our needs. However, is there a way to show a running total of costs on the form?

So I am interested in the type of registration forms that could be designed to accomplish this typical scenario for us. 

You will probably need first to create a payment or order form, here's a guide that you can refer to: https://www.jotform.com/help/165-Setting-Up-Your-First-Order-Form 

Now I am not entirely sure what you meant on "show a running total of costs on the form?". Do you simply want to see how much you earned from your form? If so, you can use this app to view how much a form earned: https://apps.jotform.com/app/jotpayments

Please note that JotForm does not process the payments, we simply integrate 3rd party payment processors, this will complete the transaction securely on their payment gateway. 

For the question about the backoffice integration, I have opened a separate thread for it. Please refer to this link instead: https://www.jotform.com/answers/871944. We will address it shortly.

Thank you.
