Inventory Help.

So i am making an inventory (well attempting), and i need some help on what to do next. I have an inventory box that pops up that is made of buttons, then i have an array that i can add things to, but where do i go from here? Here are my scripts:

Inventory Script:

 var Inventory = new Array ();
 
 var emptySlot : Texture;
 var showInventory = false;
 
 var ex1 : float = 2.8;
 var why1 : float = 5.8;
 var exBig : float = 200;
 var whyBig : float = 200;
 
 var ex2 : float = 2.8;
 var why2 : float = 5.8;
 
 
 
 function Update () 
 {
     Debug.Log(Inventory.length);
 }
 
 function OnGUI ()
 {
     if (GUI.Button(Rect(Screen.width-100, Screen.height/2-50, 100, 100), emptySlot))
     {
         if (!showInventory)
         {
             showInventory = true;
         }else{
             showInventory = false;
         }
     }
     
     if (showInventory)
     {
         GUI.Box(Rect(Screen.width/ex1, Screen.height/why1, exBig, whyBig), "Inventory");
         
         for (var x=1; x<6; x++)
         {
             for (var y=1; y<6; y++)
             {
                 if (GUI.Button(Rect(Screen.width/ex2+x*50, Screen.height/why2+y*50, 50, 50), emptySlot))
                 {
                     
                 }
             }
         }
     }
 }

Add Item Script:

 var inventoryObject : Transform;
 
 
 function Item ()
 {
     var name : String;
     var description : String;
     var myIcon : Texture;
 }
 
 
 
 function Update () 
 {
     if (Input.GetKeyDown("e"))
     {
         inventoryObject.GetComponent(Inventory).Inventory.Add(Item);
     }
 }

Where do i go from here? And can you tell me if im going in the right direction. Thanks!
