Import Adsense Script with custom fields

Hi,

and first thanks for the great plugin! Saves me a lot of time.

I have problems importing adsense scripts like

<script type="text/javascript"><!--
google_ad_client = "xxxxxxxx";
google_ad_slot = "xxxxxxxx";
google_ad_width = 336;
google_ad_height = 280;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

What do I have to do in the customs fields? I tried out many tags.

Thanks.
Kurz
