Properties Stage 3 (Swift) challenge troubles

What am I doing, I have no compiler errors, but it is telling me that I have a different equation, the only thing different is a capital letter. Can anyone figure this out

Temperature.swift 
class Temperature {
    var celsius: Float = 0.0
    var fahrenheit: Float {
        get {
            return (celsius * 1.8) + 32.0
        }
        set {
            celsius = (fahrenheit - 32) / 1.8
        }
    }    
}

You are on the right track. However in the set function you should not use the variable fahrenheit because whatever calculation you did in the get function is now saved into the newValue variable.

       class Temperature {
        var celsius: Float = 0.0
         var fahrenheit: Float {
              get {
                   return (celsius * 1.8) + 32.0
             }
               set {
                  celsius = (newValue - 32) / 1.8
            }
        }    
      }
