title: cannot update lookup field when uploading document using CopyIntoItems
body: <p>I am trying to upload a document from my local machine using the Copy.asmx webservice, the CopyIntoItems method. I can successfully upload the document and a DateTime property but I cannot update a lookup property of the document library. I am using MOSS 2007 with sp2</p>
  
  <p>The code I am using is shown below:</p>
  
  <pre><code>string[] destinationUrls = { Uri.EscapeUriString(destinationUrl) };
  
  CopySharepointService.FieldInformation dateInformation = new CopySharepointService.FieldInformation();
  dateInformation.DisplayName = "Date";
  dateInformation.Type = CopySharepointService.FieldType.DateTime;
  dateInformation.Value = DateTime.Today.ToString();
  
  CopySharepointService.FieldInformation fundInformation = new CopySharepointService.FieldInformation();
  fundInformation.DisplayName = "Fund";
  fundInformation.Type = CopySharepointService.FieldType.Lookup;
  fundInformation.Id = new Guid(fundGuidItem); // This is the GUID of the field being updated in the document library
  fundInformation.Value = "1";
  
  CopySharepointService.FieldInformation[] info = { dateInformation, fundInformation };            
  CopySharepointService.CopyResult[] result;    
  CopySharepointService.CopySoapClient CopyService2007 = new CopySoapClient("CopySoap");
  
  CopyService2007.ClientCredentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;
  CopyService2007.CopyIntoItems(destinationUrl, destinationUrls, info, fileData, out result);
  </code></pre>
  
  <p>The document is successfully uploaded but the lookup field is not updated</p>
  
  <p>Can anyone please help?</p>
