title: Selenium IDE - Extension using .js file - Error
body: <p>This is my first post as I am a newbie to Selenium. Currently I am going through book called Selenium tool : beginners guide. In the book it tells how to use Selenium IDE Extension using .js file to store your JS functions etc. </p>
  
  <p>Following example was given and and saved as user-extension.js file. I have defined file in Selenium > Option > Selenium IDE extension field. </p>
  
  <p>But when I re-start selenium I am getting following error: </p>
  
  <pre><code>"error loading Selenium IDE extensions: ReferenceError: Selenium is not defined" 
  </code></pre>
  
  <p>Example I am using is: </p>
  
  <pre><code>Selenium.prototype.doTypeTodaysDate = function(locator){
      var dates = new Date();
      var day = dates.getDate();
      if (day &lt; 10){
          day = '0' + day;
      }
      month = dates.getMonth() + 1;
      if (month &lt; 10){
          month = '0' + month;
      }
      var year = dates.getFullYear();
      var prettyDay = day + '/' + month + '/' + year;
      this.doType(locator, prettyDay);
  }
  </code></pre>
