Fade, Update, Appear using scriptaculous & prototype

[jakobmetzger]

im just trying to do these three effects in order but its not working..


function fadeupdatefade() {
new Effect.Fade('footer', { queue: 'front'});
new Ajax.Upadter('footer', 'web.html',{ onComplete: new Effect.Appear('footer')},{ queue: 'end'});
}

I dont fully understand how queues in prototype work but Ive read over quite a few tutorials. I just need it to fade a <div>, then update the information in that div and then after that just make the div appear again. im so lost on how to do this..
also I just found moo.fx, would it be more practical for me to use moo.fx instead of scriptaculous or what are the advantages?
thanks for your replys
