Why does one script not work on multiple gameobjects?

I have applied a C# script to a game object that enables / disables other game objects as they enter its trigger and it works fine. However when i copy and paste that game object or rebuild it so there is now two of the trigger objects and apply the same script to the second trigger object it registers true on the triggers but it wont run enable / disable the other game objects although the first game object will remain working just fine .

If I disable the original game object the copy works just fine?
