How do I charge for SketchUp Ruby extensions?

I would like to charge for an extension I have written. I want to distribute it via the Extension Warehouse. The extension called Window+ has been validated and is live on the warehouse right now but there is no pay for button like I hoped might be. I did mention on the testing part of the form that I wanted payment but I guess the guys who test it don’t have anything to do with to setting up of the payment option. What do I do?
