What's likely happening to you is that Breeze is not
registering the completion of the the successfully passed quiz. Do
you have the second quiz set as a "required" bit of content? If so,
the successful completion of the first quiz leaves this second
requirement unfulfilled. If the first quiz automatically begins the
second on failure, it's possible that the first quiz never
*actually* is completed, as far as Breeze is concerned. Try getting
to the last slide of that second quiz, answering the question
correctly, and closing the content before the scoring is registered
on the server, and you should see the same result. One fix is to
have an automatic forward to a single-slide "success" content item
on successful completion of the first quiz, which would allow
Breeze to appropriately register the completion. Lame, I know, but
effective! Good luck!
