Java script

Hi,

I have added this code some weeks ago, its a hotel search box and it has been visible all the time but not anymore.

The code is correct according to Agoda
<script type=”text/javascript”>
agoda_ad_client = “1410906_42393″;
agoda_ad_width = 160;
agoda_ad_height = 600;
</script>
<script type=”text/javascript” src=”//banner.agoda.com/js/show_ads.js”></script>

Any idea if I need to add some plugin in order to show the java script?

Thanks
Charlotte
