Hi Raphael,

You've used an undeclared variable which you called temperatureInCelcius - that doesn't exist. That needs to be temperature, as that's the parameter passed in:

func temperatureInFahrenheit(temperature: Double) -> Double {
  return ((temperature * 9) / 5) + 32
}

I didn't use a variable to pass the calculation first; I just returned the result directly.

I hope that makes sense.

Steve.
