Adding a tag cloud to the top of my categeory archive

Hi,

I’m using the arclite theme by digitalnature and the TDO tags Fixes plugin

This plugin filters posts in a category by tag, so I’d really like to have a tag cloud at the top of the body of the archive page to do that. I’ve found this code in the Codex. I tried putting it into the archive.php file (without modifying the code at all – I really don’t know what I’m doing with PHP), but don’t get anywhere with it.

Can anyone enlighten me?

Thanks.
