You seem to be assuming that $id_articulo will be set for you
automatically. If register_globals is on in php.ini then that
is what will happen, however register_globals is a potential
security risk (when not used correctly) and so its default
value is off since PHP 4.2

The "correct" way to access the variable passed from your first
script is to use $_GET['id_articulo'] instead of $id_articulo
