Restricting order quantity

Hi there

I have a form with a stripe integration with a drop down for quantity. I want the drop down options to be set - 4, 8 or 12 - not all between 4 and 12. Can you please advise how I implement this?

Thanks, Ali

As far as I can see, the quantity on the payment field can be set from 1, 2, 3..... and so on.

I would suggest that you add the products outside the payment field and use quantity as a dropdown field.

After getting total using a form calculation widget, you can then pass on the total to the payment field: https://www.jotform.com/help/275-how-to-pass-a-calculation-to-a-payment-field
