Multipage + double event switcher

Hi to all,
I'm building a multipage form in which I'm adding Event Switcher action in order to jump pages conditionally. Actually in the first page there are text boxes and a radio box which should trigger the first Event switcher, according to this FAQ

I named the options like this: soci=soci APIS and nonsoci=non soci and these are the names I set also for the events in the Setup Tab; I think I put the right code in the Event switcher action, but it doesn't work;

'nonsoci' page contains some more fields to fill in

I need also a second Event Switcher inside 'nonsoci', in case they wish to insert data of their company in the bill instead of the individual person, so I dragged my second switcher in the event (in which there is a checkbox instead of a radio button as a trigger). Also this event does not work.

Any suggestions? Thanks, Davide
