So you're gonna want to leave the line declaration as how it is at the beginning. Your last name check is spot on (Except you might want to use <= instead of just <). What you're returning however is what the line is going to be, whether that's 1 or 2. So check what you're returning, make sure it's only 1 or 2, and see if it clicks
