problem with plugin event calendar 3
 

I use event calendar 3 with widget event on inner sidebar.
its working but when i try to use more then 3 event to show I dont know where to put the code to see more event.
in event calendar forum I see that I have to insert code in sidebar.php (simple php code)
so I insert this code in footer.php because athaulpa use this thing for the sidebar.
but nothing change, see www.pdumbertide.it
to understand
thanks
code to insert

<li>Events <?php
ec3_get_events(
'7 days', // limit
'%DATE%: <a href="%LINK%">%TITLE%</a>', // template_event
'' // template_day
);
?></li>
