Answer 1

Open up the JavaScript console

syntax error
[Break On This Error]   

)}

That points to

$('select[name="mainpage"]').live('change',function(){
    alert('ok');
)}​  <-- HERE

You switched them! Correct order is })

$('select[name="mainpage"]').live('change',function(){
    alert('ok');
});
