Stripe Integration - Max Price

We are charging for an event, the cost is $5 per person.

However, there is a maximum amount that we will charge which is $20. In other words, if a family has seven people, they will only be charged $20, not $35.

We will get the name of each person attending on the form.

What is the best way to accomplish this using the stripe checkout integration for payment?

You can set up options outside the payment field using Single or multiple choice fields - assign calculation values to each option.

Then use the form calculation widget to calculate the total and pass on the total to the Stripe payment field: https://www.jotform.com/help/275-how-to-pass-a-calculation-to-a-payment-field/.

However, please let us know what will be the total price if there are 2, 3, 4, 5, 6 people.
