Uncaught ReferenceError: artoo is not defined

[pradeepbn]

I am getting this error in popup.js at here:

artoo.on('ready', function() {
var tablink = "";
$('#get-data').click(function () {..}
});

I am using this in the chrome extension popup.js. Here is the manifest.json http://pastebin.com/B7w4M64g

Can you help me resolve this?

With only this information @pradeepbn, I am afraid I cannot help you.

@Yomguithereal below are more details:

artoo.on('ready', function() {
      var tablink = "";
      $('#get-data').click(function () {
          chrome.tabs.getSelected(null,function(tab) {
                  tablink = tab.url;
          });
      var showData = $('#show-data');

      var nameList = artoo.scrape('.profile-overview-content h1', {
          name : 'text'
      });            
  });

This is in the popup.js which is equivalent to "content.js". I am assuming that artoo.scrape should work here because it works in the context of "artoo.on()". Is my assumption right? Below is the tree structure of my plugin directory:

Thanks in advance. Please let me know if you need additional information.
