Stripe integration - update quantity field

Is there a way to update the quantity of a product on the Stripe integration based on the answers that the customer provide in a field of the form.

Thanks.

Unfortunately, it is not possible to pass quantity value from a field outside the payment integration to the payment field.

As a workaround, you can configure these products outside the payment field:

1) You will need to split your products into native fields such as "Single choice" or "Multiple Choice" fields, and assign a value to each option: https://www.jotform.com/help/301-How-to-Assign-Calculation-Value 

2) Then perform the calculations: https://www.jotform.com/help/259-How-to-Perform-Form-Calculation-Using-a-Widget 

3) Pass the total to the payment field: https://www.jotform.com/help/275-How-to-Pass-a-Calculation-to-a-Payment-Field 

Let us know if you have further questions.

Thanks.
