Jquery and Regular Javascript Interference -

im building site in joomla , purchased content slider built in plain old javascript, built content boxes have animation on them provided jquery. right animations work, slider doesn't. wondering how page work using both. here's code

 <script src="http://code.jquery.com/jquery-1.4.4.js"></script> <script>jquery.noconflict(); $(document).ready(function() {    //settings    var opacity = 0.5, toopacity = 1, duration = 350;    //set opacity asap , events    $('.opacity').css('opacity',opacity).hover(function() {        $(this).fadeto(duration,toopacity);      }, function() {        $(this).fadeto(duration,opacity);      }    );  }); </script> 

try calling after libraries loaded:

jquery.noconflict(); 

also, try replacing jquery ready function this:

jquery(document).ready(function($){ 

this passes $ shortcut jquery code block, should still avoid conflicts outside it.

you can read on subject here in jquery docs.
