More elaboration on combining words please...

So I entered this code in the text box?
<tags>
<tag url="http://tagul.com" weight="130">Seperate words 1</tag>
<tag url="http://google.com/search?q=words" weight="18">Seperate words 2</tag>
<tag url="http://google.com/search?q=etc" weight="12">etc</tag>
</tags>

Now where do I put the words I want to add to the word cloud??!

thanks!
