Purchase cost information

Hello there,

I know you can display information about purchase costs for each galley (as seen in the galley_link.tpl). But I don’t know how. I’ve added information in the distribution settings about payments. I have also activated subsriptions and added a reader fee. But it doesn’t change the frontend. The information isn’t displayed on the article page or the “About the journal”-page.
What am I doing wrong?

I am using currently version 3.1.0.

Kind regards
