C# and JavaScript Event system causing

I'm having problem with my event system. I set it up in C# like this public delegate void FirePressed(); public static event FirePressed Fire;

     public delegate void AimPressed();
     public static event AimPressed Aim;
     
     public delegate void ActionPressed();
     public static event ActionPressed Action;
     
     public void ButtonPressed(string ActiveButton)
     {
         switch(ActiveButton)
         {
             case "Fire":
                 if(Fire != null)
                     Fire();
                 break;
             case "Aim":
                 if(Aim != null)
                     Aim();
                 break;
             case "Action":
                 if(Action != null)
                     Action();
                 break;
         }
     }

and my javascript code contains this in it

 ButtonControl.Aim += ADS;

but unity keeps saying that ButtonControl (the name of the c# script) is an unknown identifier. Does anyone know how to get the JS script to recognize the c# script

FYI I followed all of the compiler procedures.
