the problem with "google structured data testing tool"

I am having trouble with setting up Authorship in Google+. I’m getting these three errors on single posts with the Structured Data Testing Tool :

Warning: Missing required field “entry-title”.
Warning: Missing required field “updated”.
Warning: Missing required hCard “author”.

and

This information will not appear as a rich snippet in search results, because it seems to describe an organization. Google does not currently display organization information in rich snippets
At least one field must be set for Hcard.
Missing required field “name (fn)”.

Help please!
