By default Wordpress doesn't allow Javascript code pasted directly to a page or post, but we can add it by creating a Custom Page template.
 
1.- Inside your Dashboard  go to  Appeareance -> Editor 

2.- In the right corner select the theme you are going to use:

3.- Search for the Page Template ( Page.php ) and open it:

4.- Open a text editor such as Notepad, create a new file call it "conducttr_widget_page.php" and paste the code in it.
 
5.- After the line get_header() paste the next lines of code and save the file:

<?php
/*
Template Name: Conducttr Widget Page
*/
?>

<script src="http://cdn.jquerytools.org/1.2.7/full/jquery.tools.min.js" type="text/javascript"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.2/jquery-ui.min.js"></script>
<script type="text/javascript" src="https://conducttr-a.akamaihd.net/ext/js/chosen.jquery.min.js"></script>
<script type="text/javascript" src="https://conducttr-a.akamaihd.net/ext/js/conducttr-widget-2.6.js"></script>
<link rel="stylesheet" href="https://conducttr-a.akamaihd.net/ext/css/chosen.css" type="text/css">


<script type="text/javascript">
//selector for the widget container
var widgetElement = "#conducttr-widget-solo-signup";
</script>

6.- Upload the file to your web host to the next path:
 
http://www.mydomain.com/wp-content/themes/ThemeYouAreUsing/
 
7.- Inside the wordpress Dashboard create a new page, select the Text tab  and paste the HTML code of your Conducttr Sign-up widget.
 
8.- In the the left column Page Attributes in the field Template select Conducttr Widget Template and Save the page.
