A question about rich snippets

I hate bugging you guys about the same thing again, and want to try do more to resolve the issues myself.  I suspect my problem with the rich snippets this time may have to do with a tag which may not have been closed somewhere.  There must be a tool to check this, but I couldn`t find it. Anybody know of one?
