Hi all:
I am trying nathelper module
refer to (http://www.informatik.uni-bremen.de/~prelle/terena/cookbook/main/ch04s07.html)
 
but when run ser , it say unknown command , missing load module?
and the error is
 
if (method == "REGISTER" || ! search("^Record-Route:")) {
and each line when use "search" , always says it has errors
 
can anyone give me any idea what was wrong ?
thanks
 
jimmy
