Assign script into another script in Inspector

Question

 //// In Action.cs
 using UnityEngine;    
 using System.Collections;    
 public class Action : Object {
     public string mTest;
 }

 //// In Actor.cs
 using UnityEngine;
 using System.Collections;
 public class Actor : MonoBehaviour {
     public Action mAction;
 }

 //// In ActorOnInspector.cs
 using UnityEditor;
 using UnityEngine;
 [CustomEditor(typeof(Actor))]
 class ActorOnInspector : Editor {
     SerializedObject actor;
     SerializedProperty action;
     void OnEnable ()
     {
         actor = new SerializedObject(target);
         action = actor.FindProperty("mAction");
     }
 
     public override void OnInspectorGUI () {    
         Actor editing = target as Actor;    
         Object before = editing.mAction;    
         EditorGUILayout.PropertyField(action);    
         if (action.objectReferenceValue as Action != before)    
             editing.mAction = action.objectReferenceValue as Action;
         actor.ApplyModifiedProperties();
     }
 }

Could anyone please tell me why I can't drag Action.cs(In Project window) to Actor::Action property field(In Inspector window)? Thank you.

You can't just call a script or assign a script to another script. If you want to call a script and edit it in another script it has to come from an object. Use this as an example to get a script from an object (C#). P.S. referencing a script from inside a function makes that variable only work in that function.

 Using UnityEngine;
 Using System.Generic;
 
 void Update()
 {
     GameObject player = GameObject.Find("Player");
     scriptOnPlayer plrScript = player.GetComponent<scriptOnPlayer>();    
 }

You can't assign a script to a variable. Simple as that.

If I declare Actor.mAction as Object not Action, then I can drag Action.cs to it. But it can't cast back to Action type. Anything thought?
