  41.         error: isFollowedErrorHandler  
  42.     });  
  43. }   
  44. function isFollowedSuccessHandler(data) {  
  45.     var stringData = JSON.stringify(data);  
  46.     var jsonObject = JSON.parse(stringData);  
  47.     if (jsonObject.d.IsFollowed === true) {  
  48.         alert('The user is currently following the document.');  
  49.     } else {  
  50.         alert('The user is currently NOT following the document.');

  54.     alert(errorMessage);  
  55. }   
  56. function getQueryStringParameter(paramToRetrieve) {  
  57.     var params = document.URL.split("?")[1].split("&");  
  58.     for (var i = 0; i < params.length; i = i + 1) {  
  59.         var singleParam = params[i].split("=");
