pdlua compile and load well here I think, console says:

lua 0.5 (GPL) 2008 Claude Heiland-Allen <claudiusmaximus at goto10.org>
lua: compiled for pd-0.40 on Jul 16 2008 11:41:16

After that I wrote a little pd_luax object called lspell.pd_luax and 

local LSpell = pd.Class:new():register("lspell")

function LSpell:initialize(name, atoms)
    self.outlets = 1
    self.inlets = 1
    return true

function LSpell:in_1_symbol(s)
    pd.post("received :" .. s)
    word = get_word_from_inlet()
    cmd = "aspell -c " .. word
    p = assert(io.popen(cmd))
    result = p:read("*all")

I know there is no output yet but the code is bugging at the 
get_word_from_inlet() function.
When I do :

[symbol toto(

pd prints:

received :toto
error: lua: error in dispatcher:
[string "lspell.pd_luax"]:14: attempt to call global 
'get_word_from_inlet' (a nil value)

I have no really idea of the way pdlua manage functions and everything. 
Must I dig more into the pd_lua examples or is this only a lua problem I 
can handle if searching universal lua docs?

Thanks for your answers,
