sunkywinkist on "Editor Menu is missing"

hai ladies, thanks for your response.

i have an intention to add on some html code at my current template.
Basically, it an advert html where i wish to put amongs the widget.

Ive tried Widget-->Text--> Paste this code

<!-- nuffnang -->
<script type="text/javascript">
nuffnang_bid = "03e86386d125d5c21d4c7c71b01ad148";
document.write( "<div id='nuffnang_ss'></div>" );
(function() {
var nn = document.createElement('script'); nn.type = 'text/javascript';
nn.src = 'http://synad2.nuffnang.com.my/ss.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(nn, s.nextSibling);
})();
</script>
<!-- nuffnang-->

But the its failed.

In other hand, where actually i can find the EDITOR link?

Thanks!
