converted array item to string returns "s,tri,ng" with commas?

Im trying to make an inventory. Everything works perfectly except for one thing, when scrolling between items i noticed all "strings" listed are seperated like this: (m,e,yo,u,h,er,hi,m). I dont want commas at all.. can anyone see why this random comma appears to be seperating my strings? i use Unityscript / Javascript.

 var itembagCursor : int = 0;
 var itembagCursorMax : int = 0;
 var selectedItem;
 var selecteditemname;
 
 function Start(){
 
     Master.itembag.AddRange(Array("potion","shard","antidote")); //add item to inventory
     itembagCursorMax = itembagCursorMax + 2;
     Master.inventory.AddRange(Array("key","key","ammo","ammo")); //add multiple items
 
     Master.inventory.Sort(); //sort inventory
 
     Master.inventory.Remove("ammo"); //remove first instance of item
 
 }
 
 function Update(){
 selectedItem = Array(Master.itembag[itembagCursor]).ToString();
     if(Input.GetKeyDown(KeyCode.LeftArrow)){
         itembagCursor = itembagCursor - 1;
     }
     if(Input.GetKeyDown(KeyCode.RightArrow)){
         itembagCursor = itembagCursor + 1;
     }
     if(itembagCursor > itembagCursorMax){
         itembagCursor = 0;
     }
     if(itembagCursor < 0){
         itembagCursor = itembagCursorMax;
     }
 }
 
 function OnGUI(){
     GUI.Label(Rect(0,0,400,50), "Inventory: " + Array(Master.inventory)); //display inventory by converting it to an array
     GUI.Label(Rect(Screen.width/2 - 200,Screen.height - 50,400,50),selectedItem);
 }
