Hi John,

You want to create a constant, as you have done, called fahrenheitTemp. Into that, i.e. to the right of an equals sign, use the call to the func that you've also written.

So, you assign the returned double that comes back from temperatureInFahrenheit into fahrenheitTemp:

let fahrenheitTemp = temperatureInFahrenheit(temperature: 24.0)

I hope that makes sense.


Thank you very much Steve! Problem solved with your help.

Have a great day!!
