Hey,

You can't use the setter for 'fahrenheit' this way, you need to use the 'newValue' being passed in.

set {
  celsius =  (newValue - 32 / 1.8)
}

AS Damien Watson mentions when you are using get and set function , the get function takes the input and does whatever changes you want to do it. Then the set function gets the modified value from the get function and assigns it to a variable called : " newValue " . Hope that helps.
