[jQuery] jquery question on slideUp fadeIn and show


Hi All,
jquery noob question here. I've got a php script that runs a few
price
checker kiosks out on the sales floor at work and I've got a


element
that I can get to slide up when a product is scanned and slide back
down
after a 5 second pause with:
$(function() {
$("p").slideUp("slow");
setTimeout(function(){ $("p").slideDown("slow"); },
5000);
});
but when I change the slideUp and slideDown to fadeIn and fadeOut I'm
not
getting the element to fade in or out. Instead the element shows up
on the
screen then after 5 seconds the element appears in the position where
it
ends up after a slideUp.
Similarly if I change the slideUp and slideDown to 'show' and 'hide'
the
element again shows up in the spot that it starts the slideUp from
then
slides up after 5 seconds.
Any thoughts on what I'm doing wrong?
Thanks in advance.
