Ext.Msg.show - How determine what was clicked?

[gund]

Hi!

I`d like to answer a user for confirmation wiyh this code:

{Ext.Msg.show({
         title:'Logout',
         msg: 'Do you really want to logout?',
         buttons: Ext.Msg.YESNOCANCEL,
         icon: Ext.Msg.QUESTION,
         fn: function() {

            location.replace='http://....';// fire it if was pressed YES button
        }
    });}

I tried to make function like this:

fn: function(btn) {
if (btn == 'yes') {
//redirect...
}
}

but it doesn`t work

So how can I built this function?
Thank)

Ok)
I did it!
Here is solution if you need:

	{Ext.Msg.show({
	     title:'Logout',
	     msg: '
Do you really want to logout?
',
	     buttons: Ext.Msg.YESNO,
	     icon: Ext.Msg.QUESTION,
	     fn: function(btn) {
			if(btn == 'yes') location.href='http:/...';
		}
	});}
