I bring my apologizes. As usual, I overlooked my code.

I need to get value of variable `session.itm.value. I use

	lua_getglobal(L, "session");
	lua_pushstring(L, "itm");
	lua_pushstring(L, "value");
	lua_gettable(L, -3);
	lua_gettable(L, -2);
	cerr << lua_tostring(L, -1) << endl;

But this returs error: Cannot index string value.
