Thread:Project:Support desk/Problems with Ambox

Hello guys, I have problems with this template (or just I still don't know how to use template correctly :) ) I have Export the Template:Ambox from mediawiki.org using the Special:Export page. Then I have import XML file into my wiki with Special:Import this is the result http://caricamento.vacau.com/index.php/Template:Ambox and this happens when I use in a page like that http://caricamento.vacau.com/index.php/Sub1

What is my mystake?
