Could somebody help me?

Probably one part or two small areas are wrong. Let me know!

functions.swift 
// Enter your code below

func temperatureInFahrenheit(temperature: Double) -> Double {

let fahrenheitFromCelcius = (temperature * 9 / 5) + 32

let fahrenheitTemp = temperatureInFahrenheit(24.0)

}

Hey Paul,

You're almost there, but there are just a couple of things:

  1. You are missing the return statement in the function that the second task asked for.

  2. The function call that is to be assigned to the constant needs to be outside of the function. You can't call a function inside of itself.

Here is the corrected code for your review. I hope it all makes sense. :)

func temperatureInFahrenheit(temperature: Double) -> Double {

  let fahrenheitFromCelcius = (temperature * 9 / 5) + 32

  return fahrenheitFromCelcius
}

let fahrenheitTemp = temperatureInFahrenheit(24.0)

:dizzy:
