Make Adsense working In Nexus Description - Package When accesing the Site

Can`t Paste adsense code in Nexus, when adding a description.

When pasting Google code It doesnt show the Advertising in the community

<script type="text/javascript"><!--

google_ad_client = "ca-pub-6466962472098842";
/* Foto */
google_ad_slot = "8147751491";
google_ad_width = 728;
google_ad_height = 90;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

In Nexus > Basic settings tag

It shows when "save and reload:

<script type="text/javascript">
</script>

Instead of the whole Adsense Google code.

So it changes the code and it doesnt show the Banner in The Comunity fOrum

So please people: Make it work
