Sorry bud. Not sure what's wrong with your setup, but clearly something is. The script is a direct copy off my device, where it's working just fine. The only thing you should need to change is in the very top of the script, to get your local weather instead of my local weather.

But out of the box, it should just run. You're on a N900 right? Not an N9. This is for N900.

Also, this assumes you're using my script. The one in the top post is quite old. You should be using the latest one, from this post.
