Are there any instructions on how you would set up the buying functionality? For example, I have a radio station and I would like for our listens to buy a show. I have activated the buy parameter in the tool and I see the buy button, but do I need to deactivate/activate the download parameter. Not for sure what steps I need to take first. Another example, does the button only show when there is a price on the song? Any advice on what steps I need to take would be great.
