Charging a dynamic amount to a user using saved CC Stripe

Hi, I’m building am building an app in which users book lessons with teachers and get charged when the lessons have begun.
I’m trying to get the stripe plugin to charge a user for a lesson they purchased after a designated time. I figured out how to get it to recognize that the dynamic time has passed but am having problems telling it the dynamic amount to charge. I’m linking the amount section in the “charge a user using saved CC” workflow to a data field that evaluates to a number. The data on this number is saving correctly in the database but when I run the action the charge a user workflow fails and says Invalid Payment Amount: Null". If I use a static amount in the amount section the workflow runs correctly. Any help on what I could be doing wrong would be much appreciated. I’ll link some images of my workflows and errors below.
