Add calculation based on product and kilometer

I would like to know if it's possible to have a calculation on the form.
What I mean is that my product has a price but total price is after the km between both location added on the form, is this possible?

Unfortunately, it is no longer possible to calculate a price from another field and the payment field.

As a workaround, please use Multiple Choice field to list out your products, assign calculation values, then add a Form Calculation widget to calculate the total and lastly, pass the total into your payment field.
