[ns] invalide command name "Agent/myUDP" during using smallkoEvalvid

[anas]

dear NS users,  
I am working on video traffic over MANET. I downloaded the
EvalVid version used for NS. In that they have created
new agent called "myUDP" agent. I follwed all the
steps given in 

http://hpds.ee.ncku.edu.tw/~smallko/ns2/Evalvid_in_NS2.htm
 when I compiled the ns again everything
was fine. But when I run the file "be.tcl" which is
given in the link only the error was:  [ code omitted because of length]
invalid command name "Agent/myUDP"
please help me
