Titolo: aiuto testo in movimento

Ciao a tutti. Sono una novellina...
ho trovato questo javascript ..l'effetto dello scroller e' molto bello.
Vorrei pero' riuscire a rallentarlo.
Sul mio vecchio 166 va benissimo, ma sui nuovi 550 e' troppo veloce.
Non so come pero'..
potete aiutarmi?
GRAZIE 1000000000000000!!!
Luisa
p.s. scusate la lunghezza del javascript.. ma l'ho incollato cosi come l'ho
trovato..

<Layer name="textanim" left=0 top=440>
</Layer>

in questa parte di codice modifica dt=20 ;
aumentandolo l'evento rallenta per accellerare diminuisci (es.dt=2 cosi'
veloce , dt=10000 lentissimo)
con netscape modifica invece l'altro dt=2 allo stesso modo di explorer.

1000 GRAZIE!!!!!!
Sei stato veramente gentile!
ho gia' provato e... funziona!!
io ho cominciato da pochissimo ad avvicinarmi al javascript.
per adesso riesco solo a personalizzare script gia' fatti che si trovano in
rete..
non sempre pero' ..come in questo caso..
ancora grazie
Luisa
