Mile High Lock Key on "Error: Missing required field "entry-title""

In Google webmaster tools, I'm getting these rich snippets errors when I am previewing url's such as:
http://www.denver-locksmith.net/blog
Or
http://www.denver-locksmith.net/category/locksmith/

I'm getting this errors:
Error: Missing required field "entry-title".
Error: Missing required field "updated".
Error: Missing required hCard "author".

These errors do not appear when I'm previewing only the home page url such as:
http://www.denver-locksmith.net

Any suggestions? Thanks.
