Tabs effects doesn't work

Tabs effects doesn't work

Hi,

I'm trying to use JQuery in my site and it doesn't work.

I've downloaded 1.8rc1 and here's my call:

  1. <link type="text/css" href="http://www.tudosobreplantas.com.br/css/custom-theme/jquery-ui-1.8rc1.custom.css" rel="stylesheet" />
  2. <script type="text/javascript" src="http://www.tudosobreplantas.com.br/js/jquery-1.4.1.min.js"></script>
  3. <script type="text/javascript" src="http://www.tudosobreplantas.com.br/js/jquery-ui-1.8rc1.custom.min.js"></script>
Then I call:

  1. <script type="text/javascript">
    $(document).ready(function() {
     $('#resumo').tabs({ 
     fxFade: true, 
     fxSpeed: "fast" 
     });
     doCalc(); // Lunar calendar
     $("#TckrNews").jticker({
     delay: 4000,
     newwindow: true,
     url: "tickerdata.xml",
     transition: "fade",
     speed: "slow"
     });
    });
    </script>
















My tabs:

  1. <div id="resumo">
     
     <ul class="tabs-nav">
     <li><a href="#portal">Portal</a></li>



     <li><a href="#galeria">Fotos</a></li>
     <li><a href="#blog">Blog</a></li>
     <li><a href="#forum">F&oacute;rum</a></li>
     <li><a href="#geptsp">GEP-TSP</a></li>
     <li><a href="#lua">Fases da Lua</a></li>
     </ul>





     
     <div id="portal"></div>
  2. [...]


But it's not working (fxFade and fxSpeed). Am I doing something wrong?

My site: Tudo Sobre Plantas (to see online).

Thanks in advance!
