======================!!!!!!!!!!!!^^^^
ERROR: the index 'i' has been neither *declared* nor *defined* at this 
stage. At "best", without the package context, the function is going
to 
use whatever value a global called 'i', if any, holds, which is 
certainly not what you want. An easy fix is to define the index 'i' in 
the list of local variables (i.e. first argument of Module[]):

Module[{guess1 = guess, hacerlalista = {}, i = 1},
