Question re lua and tcp content

[FRANKS, Andy (SHREWSBURY AND TELFORD HOSPITAL NHS TRUST)]

Hi all,
  I'm an amateur with lua. I've been messing around with doing "something" when 
either an http or tcp request happens as a way of teaching myself how to do 
stuff.
Many examples use the "hello world" lua script, and call it via either :

http-request lua.script

or

tcp-request content lua.script

Which works fine; the script is called. My question though is around arguments 
.. I understand the txn  gets passed over, so one can use a script like 
this for example:

Function my_script(txn)
  ip=txn.f:src()
  core.Alert(ip)
end

core.register_action("my-script", {"tcp-req", "http-req"}, my_script)

.. and it works, but if we pass arguments, e.g.

http-request lua.script stuff
or
tcp-request content lua.script stuff

and in the script use

Function my_script(txn, arg)
  core.Alert(arg)
end
core.register_action("my-script", {"tcp-req", "http-req"}, my_script, 1)

.. http works as expected, and sends the string "stuff", but tcp just sends the 
word "content", not "stuff"

Am I missing something really obvious here!?

Thanks
Andy
