Is there a way to integrate form input with strip product or quantity?

Is there a way to integrate form input with strip form? for example if a user in option 1 selects the drop down of 3, then the strip payment data automatically updates their quinty to 3? does that make sense?

Unfortunately, this is not possible to map a form field to the Stripe product/quantity. However, this is possible to calculate a total amount based on the form fields selection and then forward it to the Stripe field.

1) How to Perform Form Calculation

2) How to Pass a Calculation to a Payment Field

Thank you.
