Location id not working

Hi

I went to wunderground.com and get my location as:
http://www.wunderground.com/q/locid:CAXX1090?

However, when I pasted that in to my shortcode
[wunderground location=”CAXX1090?”]
on my home page I’m getting the error:
The location could not be found.

I have tried various of this to try to get it to work and nothing
