cannot have child contents to be deserialized as an object

Help for a clueless newbie?

I have a web service which allows me to create a new customer on my app server.
However, I can't seem to invoke it correctly via soapUI.
I'm guessing I'm doing something wrong in my xml?

Here is the xml request I send:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:tem="http://tempuri.org/" xmlns:xxx="http://schemas.datacontract.org/2004/07/XXX.SystemLib.Interfaces">
   <soap:Header/>
   <soap:Body>
      <tem:startProcess>
         <tem:requestDetails>
            <xxx:loginRequest>
               <xxx:LoginID>manager</xxx:LoginID>
               <xxx:Password>pretendPwd</xxx:Password>
            </xxx:loginRequest>
            <xxx:Command>create</xxx:Command>
            <xxx:EntityName>customer</xxx:EntityName>
            <xxx:KeyValue>WLMT</xxx:KeyValue>
         </tem:requestDetails>
         <tem:processParameters>
            <xxx:Parameters>
               <xxx:Key>cust_id</xxx:Key>
               <xxx:Value>WLMT</xxx:Value>
            </xxx:Parameters>
            <xxx:Parameters>
              <xxx:Key>descr</xxx:Key>
             <xxx:Value>Walmart</xxx:Value>
            </xxx:Parameters>
         </tem:processParameters>
      </tem:startProcess>
   </soap:Body>
</soap:Envelope>


Here is part of the error I get:

<s:Text xml:lang="en-US">The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:boParameters. The InnerException message was 'Element Value from namespace http://schemas.datacontract.org/2004/07/XXX.SystemLib.Interfaces cannot have child contents to be deserialized as an object. Please use XmlNode[] to deserialize this pattern of XML.'.  Please see InnerException for more details.</s:Text>
...
<InnerException>
 <Message>End element 'Value' from namespace 'http://schemas.datacontract.org/2004/07/XXX.SystemLib.Interfaces' expected. Found text 'WLMT'.</Message>


SIDE NOTES:
1) In M.S. Visual Studio, I can use the web service successfully to create a new customer, so I'm pretty sure I'm doing something wrong in soapUI. I suspect my xml is wrong or insufficient.
2) If I remove the text between the <xxx:Value></xxx:Value> tags (WLMT, and Walmart), then I can invoke the web service via soapUI, and a new record is created in my app server, but without the values I want
3) Can someone clue me in to what this means?: "Please use XmlNode[] to deserialize this pattern of XML".

    I've found a way to make the XML work in soapUI.
    Hopefully this will be helpful if anyone else runs into the same problem.
    I was able to capture the XML being sent by my Visual Studio application to the Web Service.
    (I used a handy, free tool called Fiddler: http://www.fiddler2.com/fiddler2/ ).

    SIDE NOTE: One thing I especially noticed was xsi:type="xsd:string" in the <Value> tags.
