Exposing Enums in Custom Inspector

I'm writing a custom inspector, and I'm trying to display enums the way Unity does naturally (displaying them and of course, changing them). After playing around with it my self, I managed to display the element's names into a popup list, but selecting the values of the enums via popup list doesn't have any actual effect.

Here is what I have so far:

 var battleState : SerializedProperty;
 var bsIndex : int;
 var bsOptions : String[];

 var infliction : SerializedProperty;
 var iIndex : int;
 var iOptions : String[];
 
 var behavior : SerializedProperty;
 var bIndex : int;
 var bOptions : String[];

 function ShowStates()
 
    {
         //battleState.Enum = EditorGUILayout.EnumPopup("Battle State:", battleState);
          bsOptions = battleState.enumNames;
          bsIndex = EditorGUILayout.Popup(bsIndex, bsOptions);
 
          bOptions = behavior.enumNames;
          bIndex = EditorGUILayout.Popup(bIndex, bOptions);
 
          iOptions = infliction.enumNames;
          iIndex = EditorGUILayout.Popup(iIndex, iOptions);
     }
