Get browser toolbar to request querystring url

Question

Hey all

I having a little problem with the toolbar I am designing.
I'd like to have a google pagerank checker in the toolbar, the code itself to get a pagerank is in place.
But I can't get the Toolbar to retrieve the URL from the address field.?

The url I getting is to where it's on my server, but i'll want it to retrieve the current url.

Best regards
