Ho estratto questo script da un template pronto per poi adattarlo nella mia pagina.
Presa la pagina standard, ridotta alla sola area che mi interessa e provata... tutto ok!
Copio il tutto dentro una cella del mio template e nella lettura sorgente di Firefox mi da 2 errori rispettivamente ad inizio e fine pagina. Vi posto il tutto con allegati i link:
