why wont this work?!

hi,
Can someone tell me why the following code doesnt work? I am scraping one bit of data from a page, when is an url, and them im trying to follow that url and scrape some data from that page... but only the url is displaying, not the second bit of data from that url....:


iget the error  Illegal characters in path. but also the code doesnt work in getting the data.
