Signup process of Events Plugin not functioning properly

Hi

I am getting more and more requests on my blog comecrearsiunlavoro.com but no one is signing up thru the blog for any of my events and i think it is for the simple reason that
the Events + plugin is not working properly.

If i test it out for example here : http://comecrearsiunlavoro.com/eventi/2013/04/corso-come-crearsi-un-lavoro-da-0-al-2o-piano-cassola-15-04-2013-ore-2000/

The whole process is not clear which means ok i click "i am attending" but it takes me directly to Paypal in order to authorize the payment but where does the ticketbuyer actually insert his name ?

Am i getting something wrong ?

Also the Plugin should be connected to facebook right ? thru an app - i did create the app but the buttons do not show.

Can you please indicate me a step by step guide where and how i create the app that works together with the Events + plugin ?

Thank you very much
