You need to close your method definition with an end.

Also, while your code will pass the challenge just fine, it will create an array with three instances of "mos" which is not exactly what the challenge was asking for. The simplest code to pass this would be:

def add_list_items

Which simply takes advantage of the fact that ruby methods always return the value of the last line evaluated (in this case just an empty array literal).

this works, thnkas. but they wanted a return array so wouldn't

def add_list_items
return my_ary

work just as well? cause it doesnt

You don't need to assign the array to a variable as it will just immediately go out of scope when the method ends. If you wanted to be more explicit about the return you could specify it like this:

def add_list_items
  return []

But it's not necessary to have an explicit return in ruby so it's up to you.
