Where did you add that code snippet? I would remove it and add it to your site this way:
- Install the Header and Footer plugin. This plugin will allow you to add script to the
head
section of your site. - After installing and activating the plugin, go to Setting → Header and Footer and copy & paste the link into the Code to be added on HEAD section of every page field:
<script type="text/javascript" src="http://drivesafe2015.org/wp-admin/js/discount.js"></script>
