and then all i get is a null Ref

ok so i figured out that the Refrence to ZoneManager I didnot do Correctly, so the null refrence was caused as my plugin did not reconize zonemanager as loaded , now that i got that working nothing happens when doing a call

this is what i got now.

        [PluginReference]
        private Plugin MarkerManager,ZoneManager;   ​

 void PasteJail(BasePlayer player)
        {
            Vector3 pos = new Vector3(-2622, 3, 2836);

            if (ZoneManager != null) // check if plugin is loaded
            {
                player.ChatMessage("ZoneManager is loaded ");
                ZoneManager.Call("CreateOrUpdateZone", "" , "name TheJail nodecay true autolights true undestr true", pos = default(Vector3));
            }
            else
            {
                player.ChatMessage("ZoneManager is not loaded");
            }
        }

but after tis call if i check zone_list no new zone was created? any suggestions?
