updating blogger

I'm slowly bringing my blog into beta mode, and i've found this lovely code to make a label cloud in the side bar. If you want the code it is from phydeux3. I'm struggling to get a last.fm widget to work. It keeps throwing up and error that has me clueless. I'm slowly back blogging a few items too. Sorry I've not been around on the blogosphere much, I've been carried away milling on facebook.
