thanks for the help. The plugin is great.
I had another plugin for books activated totally booked. I am not sure about that. I live in Canada and I get connected to amazon.com. It is maybe because Canadians can use amazon.com
One of my plugins was interfering with it. It is working now. I was also wondering if I could change the Amazon buy buttons name so that I could include other countries for the book like Amazon England, Amazon Canada etc.
