Umm... I'm not quite sure where the confusion lies.
"Line exceeds maximum limit of 180 characters; contains 276 characters"

One of your lines of code is more than 180 characters long, it should not be.
Add a new line somewhere sensible in that very long line and the code checker error will go away.
