Streamed Asset Bundle Help

Im trying to Load a set of streamed asset bundles i created at run time. However something seems to be missing from my code. Could someone please take a look?

 //public void LoadLevelAdditively ()
  void Start()
  {
  //optimize this later as a for loop or whatever
  StreamedAssetBundlePathsList.Add(url + "Streamed-LOD0.unity3d");
  StreamedAssetBundlePathsList.Add(url + "Streamed-LOD1.unity3d");
  StreamedAssetBundlePathsList.Add(url + "Streamed-LOD2.unity3d");
  StreamedAssetBundlePathsList.Add(url + "Streamed-LOD3.unity3d");
  StreamedAssetBundlePathsList.Add(url + "Streamed-LOD4.unity3d");
  StreamedAssetBundlePathsList.Add(url + "Streamed-LOD5.unity3d");
  
  //Loop through the list and download the compressed asset bundles from the web server,
  //If the asset bundle was already downloaded and cached for any reason UNITY will skip this process
  
  foreach(string StreamedAssetBundle in StreamedAssetBundlePathsList)
  {
  var AssetBundleDownload = WWW.LoadFromCacheOrDownload(StreamedAssetBundle,5);
  
  //verify download
  if(AssetBundleDownload.error != null)
  {
   Debug.LogError (AssetBundleDownload.error);
   return;
  }
  
  //Load the current Asset Bundle into memory
  var bundle = AssetBundleDownload.assetBundle.name;
  
  //Additively Load the level into the scene
  Application.LoadLevelAdditive("CityLOD" + StreamedAssetBundlePathsList.IndexOf(StreamedAssetBundle)); //<--LOD(int) refers to the scene name
  
  }
  
  
  
  
  }
