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

In a script I had:

public class RoadManager : MonoBehaviour{
 
       public GUIStyle centerStyle;
       public GUIStyle RCP_LabelStyle;
       public GUIStyle RCP_PlusStyle;
}

and in and Editor Script I did something like this

roadmanger.centerstyle = EditorStyles.bold;
//Modified some attributes, etc etc

this saved editor information into a the object, and internal graphics, and referances to other editor info. I still want to keep these referances for my Custom inspector, so I did this to make it so the info doesn't come into a build

public class RoadManager : MonoBehaviour{
 
#if UNITY_EDITOR
       public GUIStyle centerStyle;
       public GUIStyle RCP_LabelStyle;
       public GUIStyle RCP_PlusStyle;
#endif   
}

Hopes this saves someone the headache i went through :)
