node.js - result is not coming in a call back function -

-

i have following code 

parsebookmark(user_id, category_ids,bookmark_url,function(err, result) {                 console.log("parse rersult " +json.stringify(result));                //output undefined here         });  function parsebookmark(user_id, category_ids,bookmark_url,callback) {  savebookmark(user_id,category_ids,title,bookmark_url,function(err, result) {     //result coming here     callback(result); });  }

why output coming undefined here. suggestion please.

thanks

change savebookmark call to:

savebookmark(user_id,category_ids,title,bookmark_url,function(err, result) {     callback(err, result); });

if understand code correctly console log second time err variable, undefined.
