What would make tellme a global? Here's my Lua script:

=======================
function tellme()
	io.write("This is coming from lua.tellme.\n")
end

function tellme2()
	io.write("This is coming from lua.tellmetwo.\n")
end

function witharg(n)
	io.write("Number within Lua.witharg=")
	io.write(tonumber(n))
	io.write("\n")
end

print("You shouldnt see this!")
=======================

Am I missing something? I thought the existence of a non-local function called 
"tellme" within the script called by lua_pcall() would be the global function.
