error with effects

error with effects


Hi all,
I just downloaded JQuery ui 1.5b4 to try out the morphing stuff.
I added references to jquery-1.2.4b.js and jquery.ui-all-1.5b4.js to
my html but when I load the page I get the error
Error: $.effects has no properties
Source File: file:///C:/FastBallPopin_files/jquery.ui-all-1.5b4.js
Line: 2697
This is a bummer since that's exactly the extension I want to play
with! I can't figure out what it's complaining about so I thought I'd
ask the group.
Can someone let me know how to fix this?
Thanks much!!
