Thanks V@no!!!
It looks like the objects names cannot be just numbers...
It's now working OK with Firefox... but not working for IE 6. And It isn't showing any "notice bar" saying that it halted the execution of the code... it's very strange. I tried it from another PC to see if it was my computer, but no... the problem persist.
May be some internal configuration of the Sun Java VM? May be IE is taking the screen.width value from the system start and not updating the variable when I restart IE? (in both cases, my computer and the other I changed the resolution). In Mozilla, restarting it is sufficient to update the value of screen.width .
Any Ideas?
Thanks in advance.
Best regards.

PD: If anyone wants to try it...
