Witam serdecznie,

potrzebuje formularz, w którym zależnie od liczby wybranej z menu
select (1 do 5) aktywna będzie odpowiednia liczba pól na wpisanie np.
nazwika i numeru telefonu. Odpowiednio dla jednej osoby po jednym
polu, dla 5 osób po pięć pól.

Poniższy kod działa pod FF i Opera, a nie chce działać dla IE.
Uprzejmie proszę o pomysły, co zrobić aby w IE też działało oraz
ewentualnie jak to uprościć w ogóle.
