Set payment value correctly

Here is my logic

I am trying to set the value of the payment to be taken using Stripe

But when the conditions are met, the value is not populated.

Given the above, the Card Payment value should be fixed at 50 USD but it is empty and editable.

How do I set the payment value from a field?

Hi there!

I hope you're doing well and thanks for reaching out.

You need to add a form calculation that will hold the subscription value and have it transferred to Card Payment field.

Please see this sample cloned form that I've created: https://www.jotform.com/212048536693965
