Why wont inventory wont update after or more purchases from in-game shop?

Question

The problem: When I purchase 3 more items from the shop, one item will be be left blank. I have to go to the inventory then go back to the shop every 2 purchases or else one of the items wont show.

Here's the scripts:

 public void BuildInventory()
     {
         for(loopInt = 0; loopInt <= inventoryContents.Count; loopInt++)
         {
             if(targetPath.transform.c$$anonymous$$ldCount >= inventoryContents.Count)
             {
                 if(inventoryItems.Count >= 0)
                 {
                     
                 }
             }
             else
             {
                 NGUITools.AddC$$anonymous$$ld(targetPath, itemPrefab);
                 foreach(Transform c$$anonymous$$ld in targetPath.transform) 
                 {
                     if(c$$anonymous$$ld.gameObject.tag == "Item" && inventoryItems.Count <= inventoryContents.Count)
                     {
                         inventoryItems.Add(c$$anonymous$$ld.gameObject);
                     }
                 }
                 inventoryItems[loopInt].name = inventoryContents[loopInt].itemName;
                 inventoryItems[loopInt].GetComponent<InventoryItem>().item.itemName = inventoryContents[loopInt].itemName;
                 inventoryItems[loopInt].GetComponent<InventoryItem>().item.icon = inventoryContents[loopInt].icon;
                 inventoryItems[loopInt].GetComponent<InventoryItem>().UpdateInfo();
                 gridControlScript.Reposition();
             }
         }
         Debug.Log("Inventory contains " + inventoryContents.Count + " items");
         Debug.Log("Building inventory");
     }

     public void UpdateInfo()
     {
         itemNameTag = transform.Find("Item Text");
         itemNameTag.GetComponent<UILabel>().text = item.itemName;
         itemIcon = transform.Find("Texture");
         itemIcon.GetComponent<UITexture>().material = item.icon;
     }

Just spit ballin here as I don't see quite how all the details are worked out outside of t$$anonymous$$s but it seems to me that your first nested loop is being performed rather than kicking into the else statement there.

I suspect that t$$anonymous$$s is due to the foreach loop reiterating through the list without having been cleared at the beginning. The first time it runs your foreach adds 1 to the list, then it adds 2 to the list on the second trip in through the parent loop. T$$anonymous$$s means that on the t$$anonymous$$rd trip around, your inventoryContents.Count is 3 and so is the count on your inventoryitems (1 for the first time through, and then twice for the second time through, w$$anonymous$$ch counts 1 item twice).

I would set up a dummy list in the lower scope, then set that equal to the inventory items at the end or you else statement.

 .

 .
 else
 {
 NGUITools.AddC$$anonymous$$ld(targetpath, itemprefab);
 [ListType] dummylist = new [ListType]();
  foreach(Transform c$$anonymous$$ld in targetPath.transform)
 {
 if(c$$anonymous$$ld.gameObject.tag == "Item" && dummylist.Count <= inventoryContents.Count)
 {
 dummylist.Add(c$$anonymous$$ld.gameObject);
 }
 }
 inventoryItem = dummylist;

That should get you a fresh count every time, rather than adding 1, then 2, then 3, then 4, etc. W$$anonymous$$ch will keep you out of the top if statement until you reach your inventoryContents limit.
