Need to create a chart that shows cost of licenses per user

I am working with a coworker to create a report that will show the cost of each license type that users have tied to their account. What we are trying to do is show the license associated with a user and the cost of that license in a column. The problem is that a custom calculation field isn't showing the cost of any licenses, and as a result, there is nothing to show in a report. Is there a way that we can do this, or is it something that we would need to incorporate something like Fusion into? Below is a screenshot of what we are using to call a field that should be providing license cost data, but is not. Is there something in that code that is incorrect or being called in the wrong way?

Thank you!
