That's the problem...I can't find the content to make it public. When I go to content, show all content, it's not listed. This link is a call to CB's default Terms and Condtions that appears right above the submit button.
This is a fresh install btw. Joomla 1.0.7 and CB RC2.
You need to create your own content item and place its URL in the CB parameter field. The one there is just a default one that might not be present in your installation. So create a static content item - find its URL (just display it on a page) - and copy the URL to the CB parameter field.
