new bie issues

hi all!

I am running behind an issues for a couple of days [SOAP is killing me]

Please find the code attached here - which is used to call data from a .NET
server. [I got this code from another site]

Some modifications have been done.- but am getting a result -

*"Server was unable to process request. ---> Object reference not set to
an instance of an object."*

The code follows -

require_once('nusoap/lib/nusoap.php');
        // define the soapaction as found in the wsdl
     $soapaction = "http://XXXXXX <http://xxxxxx/>";

        // endpoint address
    $wsdl = "http://xxxx.asmx?WSDL <http://xxxx.asmx/?WSDL>";
    $namespace = "http://XXXXX// <http://xxxxx//>";
    $client = new nusoap_client($wsdl, true);

        // you will find the serializeEnvelope() prototype by making a
search in nusoap.php
    $mysoapmsg = $client->serializeEnvelope('<Search
xmlns="http://XXXXX/<http://xxxxx/>
">
    <arrDate>23/10/2008</arrDate>
    <depDate>29/10/2008</depDate>
    <location>DOWNTOWN BURJ DUBAI</location>
    <persons>2</persons>
    <currency>AED</currency>
    <agentid>xxxx</agentid>
    <lngCode>xxxx</lngCode>
    </Search>','',array(),'document', 'literal');

    /* Send the SOAP message and specify the soapaction  */

    $response = $client->send($mysoapmsg, $soapaction);

    if ($client->fault) {
          echo '<h3>Fault</h3><pre>';
          print_r($response);
          echo '</pre>';
        }

    echo "<p>SOAP query</p>";
    echo '<pre>' . htmlspecialchars($client->request, ENT_QUOTES) .
'</pre>';
    echo "<p>SOAP response</p>";
    echo '<pre>' . htmlspecialchars($client->response, ENT_QUOTES) .
'</pre>';


        // start to use the result by following the structure of the SOAP
response
        // first extract the SearchResult
    $searchresult = $response["SearchResult"];
        // then you can access the Status message
    echo "Status message: ".$searchresult["Status"];
        // continue with the Result level
    $result = $searchresult["Result"];
        // wich allow access to NumRecs (number of record found)
    echo "<br>Record found: ".$result["NumRecs"];
        // extract the collection of record (object collRecord)
    $collrecord = $result["collRecord"];

    foreach ($collrecord["CRecord"] as $record){
        echo "<br>Property: ".$record["Property"];
        echo "<br>Place: ".$record["Place"];

    }


Can any one help? My skill level in SOAP is almost 0 :D

thanks!
