OAuth Failing

[Trent]

Hi,

I'm getting the following error
invalid_scope: Some requested scopes were invalid. {invalid=[http://
www.finance.google.com/finance/feeds/]}

Error 400

I'm using this string

scope = 'http%3A%2F%2Fwww.finance.google.com%2Ffinance%2Ffeeds%2F'

system "Open", "https://accounts.google.com/o/oauth2/auth?
client_id=58611226139.apps.googleusercontent.com&redirect_uri=urn:ietf:wg:oauth:
2.0:oob&scope=#{scope}&response_type=code"

It's in ruby. But I'm not sure what I'm doing to get the incorrect
scope error.

Any help would be great.

Thanks
