Want to block the Error When Tree nodes are not exapandable

Another way of doing this and getting to know what are all clicked, etc.

      for (i = 0; i < objectChildTreeViewHelp["Items"]["Count"]; i++)
      {

            my_array[i] = objectChildTreeViewHelp["Items"]["Item"](i)["Text"]
            stringText="|SoMachine Motion Overview|SoMachine Motion Overview|Releasenotes|"+stringReleaseNotesChildTextName+ "|" +objectChildTreeViewHelp["Items"]["Item"](i)["Text"]
            var stringTextArr = stringText.split("|");
            var currentItem = objectTreeViewHelp.Items("SoMachine Motion Overview");
            var menuToClick = "|SoMachine Motion Overview";
            
            for(ml = 2 ; ml < stringTextArr.length ; ml++){
                  var currentChildMenu = stringTextArr[ml];
                  menuToClick += "|" + currentChildMenu;
                  currentItem = objectTreeViewHelp.Items(menuToClick);
                  if (!strictEqual(currentItem.Items, null)){
                        objectTreeViewHelp["ExpendItem"](menuToClick);
                  }else{
                        objectTreeViewHelp["ClickItem"](menuToClick);     
                  }
            }
            
            Log["Checkpoint"]("Success: "+ my_array[i]+ " RealeaseNote Expanded Successfully")


      }
