newbie help!

["Laura Broughton" <broughtonlaura@hotmail.com>]

Hello
Im trying to follow an example of a stockquoting service from xmethods and not doing so well. I was following this tutorial: http://www.zend.com/php5/articles/php5-SOAP.php?article=php5-SOAP&kind=php5&id=4560&open=1&anc=0&view=1#Heading2  where all the info and orignal documents i was working from can be found.

So far i can do that and get a value returned, but id like to extend this so i can have more functions on the server, ive tried too do it and its all going a bit wrong! So far my server is the same as theirs, and i have tried too add a new function to return a digest of a value held in the array ( i havnt put the soapfault check on the new function to over complicate things as im fairly sure the problem is with the WSDL doc, shown after):

  function getQuote($symbol)
  {
    if (isset($this->quotes[$symbol]))
    {
      return $this->quotes[$symbol];
    }
    else
    {
      throw new SoapFault("Server","Unknown Symbol '$symbol'.");
    }
  }

  function getDigest($symbol)
  {
      $digestanswer = $this->quotes[$symbol];
      return md5($digestanswer);
  }

I think the problem is with my WSDL document though, im not good at them at all, any ideas? I think the namespaces are really confusing me, can anyone help? sorry this is a total newbie question but ive only just started learning and i dont want too give up! My edited WSDL:
