embedded code not working using .animate javascript

Hello,

Wenn I use embedded code with some javacript is doesn't work. The code works wenn I past it in a file and start it with IE.

After some searching I found that wenn the problem is in following lines in the javascript :

$("#result").animate({top: "+="+h+"px",}, 1000,function(){loadItem();}

$("#result").animate({top: "+="+h+"px",}, 1000,function(){setTimeout(function(){hideItem();},duration);} );

This lines are in a .js file on our server.

Hope someone can help.

Thanks,

Bert
