I am building a invitation page in IFrame mode, but nothing happend after calling SendRequest method, my code is like this:

fbApplication.Service.Notifications.SendRequest(users(i), "invitation", first application test ", "http://www.chinesetime.cn/chinesetime/resources/images/skin/logo.gif", True)

does anybody know anything wrong ?
