Challenge: Understanding Undefined Value returned from a Function

Hey @ghostgamer416,

  • It looks like you messed with parts of the code that you shouldn’t. The challenge said only to change the codes inside a specific area. When there is comments like this, please follow it, because you are going to mess up the test if you mess the rest of the challenge.
  • So next time, do not mess up the setup. What you can do now is just press the Reset All Code and re-do the addFive() function.
