[Plugin: JSON API] Am I doing something wrong?

Hi guys, was hoping someone would be able to lend a hand…
I’ve just installed WordPress onto my server, with my working website. I want to be able to drive in my blog posts from http://www.cavortcreative.com/blog/ to a div section on http://www.cavortcreative.com

I’ve installed the plugin, added the relevant div to my main site and added the callback script into the head;

Unsure why it’s not calling anything through the blog section on my page… could any one give me an idea why it’s not working?

Many thanks.
