How to change the tag of one object, when another object is selected.

Hello,

I have a scene with several stationary capsules. The capsules are parented to either a first sphere or a second sphere based on their position. In my scene I want to be able to turn the sphere (and the children) left or right with a GUI button when one of the capusles is selected. Everything works fine when a first object is selected and I try to rotate the spheres. My problem is, when a second, third, etc capsule is selected. The GUI buttons begin to overlap, and eventually the tags for each object and GUI buttons get so intertwined and messed up I can't continue.

I've tried the destroy GUI function which successfully got rid of the GUI buttons as well as changed the object tag. But... if I want to make 5 successive turns, I have to select the object, hit the GUI button, select the object, hit the GUI button, and so on and so forth.

I'm hoping someone can provide some advice or an alternate route to explore. Also, I've attached my code below for a little more clarity.

 #pragma strict
 
 var capsule : Transform;
 var clicked : boolean = false;
 var hit : RaycastHit;
 function Update() {
  
     if(Input.GetMouseButtonDown(0) &&
        collider.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), hit,
                         Mathf.Infinity)) {
         clicked = !clicked;
         if(tag == "Select") tag = "Unselect";
         else tag = "Select";
         Debug.Log("clicked" + (clicked? "" : " off"));
     }
     }
   
   function OnGUI()
         {
             if (tag == "Select"){
             
                 var someText = "Turn Left";
                 var otherText = "Turn Right";
                
                   if (GUI.Button(new Rect(20, 50, 100, 20), someText)){
                    capsule.parent.transform.Rotate (0, 0, 45, Space.World);
                     }
                 
                    else if (GUI.Button(new Rect(850, 50, 100, 20), otherText)){
                     capsule.parent.transform.Rotate (0, 0, -45, Space.World);
                     }
                 }
             
             else if (tag == "Unselect"){
                 }      
         }
