Can I pass calculated price to Stripe?

I am using JotForm for collecting golf tournament registration information and calculate the registration fee. No problem there. Now trying to integrate Stripe (as we already have a Stripe account). Thought I could pass the JotForm calculated cost/fee to Stripe using the User Defined Amount payment type. But the Get Price From field only shows a None option. Calculation as option is not shown. What am I missing?

I have checked your form and see that the Total Cost field is set using a Number field. In order to pass the calculated value to a payment field, it is required to be a Form calculation field. Please refer to the guide below that can help you with passing the calculation to a payment field.
