Enumaration error CS1025: Single-line comment or end-of-line expected

Hi. I was converting my code from Javascript to C#. The code works in JS and then I converted it to C# with no problem since I know both languages. However their are a few lines on my code where i do get error. These are the lines where I do and if statement with my enum. I don't know what the problem is since I did the enum according to how I saw it on the tutorial here. I don't know what the problem is and in Unity i keep getting the error referring to line 68:

Assets/Scripts/Car Control C#/Wheel.cs(68,0): error CS1025: Single-line comment or end-of-line expected

Please help I don't know what to do. Here's the code in question:

 enum WheelKind { Steer , SteerAndMotor , Motor , JustAWheel}; //types of wheel
 public WheelKind typeOfWheel;    //Object of WheelKind

 void FixedUpdate (){
         #if UNITY_STANDALONE || UNITY WEBPLAYER
 
         if (typeOfWheel == WheelKind.Motor || typeOfWheel == WheelKind.SteerAndMotor)
             TorqueControle ();
         if (typeOfWheel == WheelKind.Steer || typeOfWheel == WheelKind.SteerAndMotor)
             SteerControle ();
 
         #endif
         if (handBreakable){
             //HandBrake();
         }
         if(!carScript.braked){
             Decellaration();
         }
     }

Thanks in advance.
