Here's a few hints:

  • "Scale" still needs to take an argument
  • the type of the parameter goes in the declaration, not in the body (formula)
  • this code does a plain multiply but the original method performed a multiplying assignment (*=)
  • it looks like there's still a closing brace (}) left over from the original method
