Bug in CSS: An Overview #7?

Hi all!
I have a quick question: Is there maybe a bug in CSS: An Overview #7 (“Syntax for the wintax”)? It seems pretty simple to me and the programm says everything’s all right with my code and I can continue but it keeps marking the exercise as ‘not completed’.
Anybody else having this problem?

Could I get a couple of screenshots please?
