I have typed this sentence several times but it keeps telling me I am wrong, and I csn't get past it. Any ideas?
Ah, I see you left a message. "I type the correct answer and it tells me I am wrong" that doesn't help us or you at all.
You need to Report the sentence as "My sentence should be accepted." It's at the bottom of the exercise page. That way we get to see the sentence. And can help you or see if we have a mistake.
