title: How to pass username to a web service from sharepoint
body: <p>I'm new to Sharepoint and have tried googeling this, so sorry if I'm just being dumb.</p>
  
  <p>I have written a webservice that takes a username and returns some company related  information about the user.</p>
  
  <p>I found on google that one of the best ways to use this information is be creating a data store in Sharepoint designer.</p>
  
  <p>I have managed to get it to work by adding a default paramter, but I need to pass in the username of the person logged in.</p>
  
  <p>I found that if you select the parameter source to be Server Variable and use LOGIN USER as the name it should send that across but it's sending the default value all the time.</p>
  
  <p>What am I doing wrong?</p>
  
  <p>Many thanks for your help.</p>
