Perform calculations in form

We are actually working on a new form called Scooter Rental, in that form the total should be the amount of days * for the equipments selected, how can I set that up?

Thank you

The amount of days can be calculated with a Form Calculation widget field:

However, we cannot pass it to the PayPal payment field.

As a workaround, you may rename the product quantity to the number of days.

The form user will need to manually select the number of days (quantity) in the payment field.

Alternatively, you can use the regular fields to calculate the total amount:

Then, pass the calculated total amount to the payment field.
