How do I fix compliance error?

Copy and paste correct script please It is a little faster. Thanks

Error is:

Assets/Editor/CopyMoodBox.cs(9,12): error CS0246: The type or namespace name `MoodBoxData' could not be found. Are you missing a using directive or an assembly reference?

Script is:

using UnityEditor; using UnityEngine;

class CopyMoodBox : ScriptableWizard {

 static MoodBoxData data;
 
 [MenuItem ("Tools/CopyMoodBox")]
 static void Copy () {
     if (!Selection.activeGameObject)
         return;
     data = ((MoodBox)Selection.activeGameObject.GetComponent<MoodBox>()).data;
 }

 [MenuItem ("Tools/PasteMoodBox")]    
 static void Paste () {
     if (0==Selection.gameObjects.Length)
         return;        
     
     MoodBoxData copyHere;
     int i = 0;
     
     foreach (GameObject obj in Selection.gameObjects) {
         if (obj.GetComponent<MoodBox>()) {
         copyHere = ((MoodBox)obj.GetComponent()).data;
     
         copyHere.noiseAmount = data.noiseAmount;
         copyHere.colorMixBlend = data.colorMixBlend;
         copyHere.colorMix = data.colorMix;
         copyHere.fogY = data.fogY;
         copyHere.fogColor = data.fogColor;
         
         i++;
         }
     }
     
     Debug.Log ("Mood Box pasted " + i + " times.");
 }
