Am trying to perform a basic insert to custom list item when an item added from sub-site source list but the insert command don’t execute. Any idea?

Elememnts.xml setting to hook the receiver:

<?xml version="1.0" encoding="utf-8"?>     <Elements xmlns="http://schemas.microsoft.com/sharepoint/">     <Receivers ListUrl="Support/Lists/Suggestions" Scope="Web">          <Receiver>          <Name>EventRcvr_MPW_SuggestionItemAdding</Name>          <Type>ItemAdding</Type>          <Assembly>$  SharePoint.Project.AssemblyFullName$  </Assembly>          <Class>PortalV2.EventRcvr_MPW_Suggestion.EventRcvr_MPW_Suggestion</Class>          <SequenceNumber>10000</SequenceNumber>   </Receiver> 

Insert code:

 public override void ItemAdded(SPItemEventProperties properties)  {       base.ItemAdded(properties);       this.EventFiringEnabled = false; //prevent multiple insert              using (SPWeb web = properties.OpenWeb())             {                     SPList list = web.Lists["MyPortalWinner"];                     web.AllowUnsafeUpdates = true;                     SPListItem item = list.Items.Add();                     item["Title"] = "SUGGESTION";                     item.Update();                     web.AllowUnsafeUpdates = false;               }             this.EventFiringEnabled = true; //reset     }
