You can report it using "my translation should have been accepted" button. That is if you are sure your answer should have been accepted.... I have added this word order here.
Thanks for the quick reply. I am familiar with that button, but since I am a complete beginner in Czech I never know for sure whether my word order is incorrect or not. Hence my question.
And I am sure it must be a near impossible task to include all thinkable answers. :-)
