Unity3d Error---Build failed : Asset is marked as don't save

1. publicclassRoadManager:MonoBehaviour{
2. publicGUIStyle;
3. publicGUIStyle;
4. publicGUIStyle;
5. }

and 

1. .=EditorStyles.;
2. //Modified some attributes, etc etc

this saved editor information into a 

1. publicclassRoadManager:MonoBehaviour{
2. #if UNITY_EDITOR
3. publicGUIStyle;
4. publicGUIStyle;
5. publicGUIStyle;
6. #endif}

Hopes this saves someone the headache i went through :)
