Why doesn't "preview" button show me my compiler errors on a challenge?

When taking a challenge and getting an error code, it says to click on the preview button to show what i have entered incorrectly. My preview button does nothing.

Hi, Steve. Sometimes, the code you write has no compiler errors but the challenge tells you that it's incorrect because it's not what the challenge is specifically looking for. When you don't see any errors in the Preview section, it means that your code has no compiling errors ;)
