Subject: Can't use variable from cgi with hpricot

I'm trying to get a url from a form and return the page title of said
url. I'm using cgi to get the web address from the url, which looks like
this:

http://somesite.com/result.rhtml?link=http%3A%2F%2Fpracticalpedal.com

The result page embedded ruby looks like this:

<%
require 'rubygems'
require 'cgi'
require 'open-uri'
require 'hpricot'

cgi = CGI.new

@linky = cgi['link'].to_str

@result = open(@linky)
@doc = Hpricot(@result)
@title = (@doc/"title").inner_html
@result.close

puts @title
%>

This works if I assign the @linky variable like so:

@linky = "http://practicalpedal.com"

But not when getting it with cgi. I'm very new at all of this, as is
probably obvious, but I can't figure this out. Any pointers in the right
direction would be appreciated.
