hi,
you have to handle an extra parameter in your getdata function which should
be a
callback function to call when ajax request is complete.

your getdata should then look like :
function getdata(whatdata,whatdiv, callBack) {
  new Ajax.Updater(whatdiv, someURL, {
   parameters:whatdata,
   onComplete: callBack
});
}

you could then call it that way:

getdata(whatdata,whatdiv, function(){
  new Effect.Slidedown(whatdiv);
});
