How to build udp receiver?

I want to build a data that came through udp receiver, but when I tried to build the udp receiver block I got this error message. Is there any one who can help me on this? Is there anyone who can give me answer to this or direct me to one who can give me assistant please?

 I am trying to build a udp block and get this error:
