Answer 1

The reason this is happening is because of how you are storing your CMS name.  You are storing the CMS name in the request object
String[] tab_schamp = request.getParameterValues("schamp");
String[] tab_stype = request.getParameterValues("stype");
String[] tab_svaleur = request.getParameterValues("svaleur");
but when you change the zoom level - a postback occurs and your code is run again.  However this time the request object is empty and there's no values to retrieve.
So your options are:
1. After you run through the first time, save the report / reportsource in session and just retrieve that on each subsequent postback.   This is a common technique.
2. Save the values that you retrieved from the request object into something that persists between postbacks - such as session or a cookie.
