Help! Riuscite a dirmi come mai 'sto codice (con un buon effetto tra l'altro) di scroller verticale, all'interno di questa pagina non funziona?!
Per voi che ci capite di Javascript dovrebbe essere una bazzecola risolvere 'sto mio dilemma scespiriano (si si, si scrive così...)
HELP ME!!!

/*******************************************
Vertical Scroller (Marquee Replacement) v-1.3
Brian Gosselin - http://scriptasylum.com
Version notes:
V-1.0: Initial release.
V-1.1: Fixed bug in NS6 where page shrinks and grows as
content scrolls. You no longer have to specify
content height, the script does this for you.
V-1.2: Fixed a bug in NS4 where scrolling content would
dictate the bottom boundary of box script.
V-1.3: Added selectable support for pausing the scrolling
when box moused-over.
*******************************************/
//ENTER CONTENT TO SCROLL BELOW.
var content='You <s>can</s> "put" most any type of HTML <font color="red">in</font> here.
V-1.1: This script has been updated to fix a bug when used in Netscape 6.2. This bug caused the page to "grow" and "shrink" as the content scrolled in and out of view.
V-1.2: Fixed a bug in Netscape 4 which caused the scrolling content to dictate bottom script boundary.
Also, you no longer have to specify the scrolling content height, the script does this for you.
V-1.3: Added support for pausing the scrolling when box moused-over. This feature is selectable.';
