[jQuery] IE problems with jQuery

[Tbone]

Greetings...Be gentle, a newbie here...

I've got a web app using jQuery that runs wonderfully with FF3, but
fails miserably w/IE7.  I think it has something to do with the
initial ajax calls I'm making....

Relevant code:
</body>
  <script type="text/javascript">
  $(document).ready(function(){
    var host="http://zvm/";;
    loadUsers(host);
  })
  </script>
function loadUsers(host)
{
  $.ajax({
    type: "GET",
    url: host+"userlist.cgi",
    dataType: "jsonp",
    success: function(data) {
      var el1=document.getElementById("row1");
      el1.innerHTML=data;
      makedragdrop();
    },
    error: function(request, settings, exception) {
      errmsg = "Error requesting page " + settings.url;
      if (exception) {
        errmsg += " - Exception was:"+exception;
      }
      logWrite("E",errmsg);
    }
  });
}
===================
The "GET" call is being made, the problem seems to be in the "success"
processing.  DebugBar pops up a message:
Line: 3
Character: 1
Code: 0
Error Message: Syntax error
URL: http://ganymede/

This isn't very helpful as in Line 3 of what??/

Any explanations for a dumb newbie?

Thanks,
Tbone
