How can I limit Shipping to a specific amount?

Please check out this form: https://form.jotform.com/twchamps/bl-label-order

I want to charge $2 Shipping per item, but max out the Shipping at $16.

How can I do this?

We would like to apologize for any inconvenience. I'm afraid that the option you are looking for is not available within the payment field of the form. There isn't an option to limit the shipping cost based on the number of products selected.

The only solution that I can think of right now that would meet your requirements is to recreate the product list of your form outside the payment field using regular or basic form fields. The calculation for the total amount (sub-total + shipping) can be done using the Form Calculation widget and/or conditions. And then, the total amount can be passed to the PayPal payment field in your form.

If that could work for you and if you need assistance setting-up your form, please do not hesitate to let us know and we will be glad to help you further.

Still not seeing how to automatically stop the shipping cost at $16.

I have created a custom calculation here so you can see how it works. Please check if the calculation on my cloned form is what you need. I have implemented a cap of $16 on the "Shipping total" field which will take effect once the "Shipping" field is greater than $16.
