Buonasera...
codice:
<frameset rows="15%,85%">
	<frame name="" marginwidth="10" marginheight="10" noresize>
	<frameset cols="22%,78%">
		<frame name="" marginwidth="10" marginheight="10" noresize>
		<frame name="" marginwidth="10" marginheight="10" noresize>
	</frameset>
</frameset>
Non ottengo la divisione in frame, come mai?

Cosa sbaglio?
