$flavors = get_flavors_by_likes($number);
takes a number, but where is it defined? What does the function comments say? What do you think the code does? What happens if you pass a number into the function? The question mentions '3'. Why not try calling it with that?
Please let me know how you get on. iain

Front End Web Development Techdegree Graduate 32,425 PointsI was stuck on this too. If you assign (in the controller code) the number 3 to the $number variable it will work:
$number = 3; $flavors = get_flavors_by_likes($number);
