Ciao longlook,

quando posti del codice mettilo tra [CODE] e [/CODE] (non nel quote altrimenti non si riesce a copiarlo)
tu ti riferisci al form in questo modo

codice:

document.forms[1]

ma di form nella pagina ne hai uno solo, quindi sarebbe

codice:

document.forms[0]

oppure, visto che il form ha un nome

codice:

document.form1

ce ne sono parecchie di cose che non vanno.
le if devono avere sempre le parentesi per le condizioni
per verificare un'uguaglianza si usa ==
la or in javascript ||
però se devi verificare che almeno uno dei due non sia vuoto devi usare una AND che sarebbe &&
l'action puoi metterlo direttamente nel form
l'evento del submit è "onclick" e non "on click"
la funzione sarebbe meglio richiamarla all'onsubmit
insomma sarebe meglio fare la funzione così

codice:

function controllo(ff){
	if(ff.regione.value=="" && ff.posto.value==""){
		alert(" necessario compilare il i campi regione o città");
		return false
	}
	else return true
}

e richiamarla così

codice:

<form name="form2" method="get" action="pa.asp" onsubmit="return controllo(this);">
