Get the Linked Item Page number in the Link Panel

Hi,

I need to get the Page number of the Linked item in the Link Panel. I have used the following script. But it shows an error. Please guide on me to get the Page number of the linked item.

// get the active document
var doc = app.activeDocument;

// loop through all the links in the document
for (var i = 0; i < doc.links.length; i++) {

  // get the current link object
  var link = doc.links[i];

  // get the link properties
  var name = link.name; // name of the link
  var path = link.filePath; // path of the linked file
  var status = link.status; // status of the link (e.g. missing, modified, OK)
  var size = link.size; // size of the linked file in bytes
    var page = link.page;
  alert("Link name: " + name + "\nLink path: " + path + "\nLink status: " + status + "\nLink size: " + size + "\npage: " + page) ;

}
