Changing cursor over multiple objects

Hi guys, in my game I have multiple turrets spread in the map and I want the cursor to change whenever i pass the mouse over a turret it should change the normal cursor to a attack cursor that I have. I was able to get it working when I had the script only in one turret but by adding the working script to other turrets whenever I passed the cursor over the second turret it would just get a second cursor behind the main cursor, so I decided to split the script in two. The main script ("Main_Cursor") goes to the Main Camera, this is where i have the textures of the cursors and it should get data from the secundary script ("Turret_Cursor") that is located in every turret. This way whenever I pass the mouse on the turret the secundary script should send to the main script that I passed the mouse trough the tower and the main cursor should change to the attack cursor.

Script Main_Cursor:

 var cursor : Texture2D;
 var link : Texture2D;
 var normal : Texture2D;
 
 function Update()
 {
  cursor = GetComponent(Turret_Cursor).cursor;
 }
 
 function Start()
 {
     Screen.showCursor = false;
     cursor = normal;
 }
 
 function OnGUI () 
 {
     var mousePos : Vector3 = Input.mousePosition;
     var pos : Rect = Rect(mousePos.x,Screen.height - mousePos.y,cursor.width,cursor.height);
     GUI.Label(pos,cursor);
 }

Script Turret_Cursor:

 function OnMouseOver ()
 { 
     Screen.showCursor = false; 
     GetComponent(Main_Cursor).cursor = GetComponent(Main_Cursor).link; 
 } 
 
 function OnMouseExit ()
 { 
     Screen.showCursor = false;
     GetComponent(Main_Cursor).cursor = GetComponent(Main_Cursor).normal; 
 }

Any solution?
