Linkedin authentication failing

I hope am am posting this in the proper place.

I am trying to work through the tutorial make your first LinkedIn API call using OAuth 2.0.

http://developer.linkedin.com/documents/authentication

a. Generate Authorization Code by redirecting user to LinkedIn's authorization dialog

https://www.linkedin.com/uas/oauth2/authorization?response_type=code
&client_id=YOUR_API_KEY
&scope=SCOPE
&state=STATE
&redirect_uri=YOUR_REDIRECT_URI

Filling this out:

https://www.linkedin.com/uas/oauth2/authorization?response_type=code
&client_id=123456789
&scope=r_basicprofile%r_network%
&state=abcdefghi
&redirect_uri=http://www.socialinnovationlab.net

which gives a uri of

https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=123456789&scope=r_basicprofile%r_network%&state=abcdefghi&redirect_uri=http://www.socialinnovationlab.net

And this gives the linkedin auth form as it should.

b. Request Access Token by exchanging the authorization_code for it

https://www.linkedin.com/uas/oauth2/accessToken?grant_type=authorization_code
&code=AUTHORIZATION_CODE    ****I think this is the above uri?******
&redirect_uri=YOUR_REDIRECT_URI
&client_id=YOUR_API_KEY
&client_secret=YOUR_SECRET_KEY

I have:

https://www.linkedin.com/uas/oauth2/accessToken?grant_type=authorization_code
                                       &code=https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=123456789&scope=r_basicprofile%r_network%&state=abcdefghi&redirect_uri=http://www.socialinnovationlab.net
&redirect_uri=http://www.socialinnovationlab.net
&client_id=123456789
&client_secret=1212121212

Which givies a uri of:

https://www.linkedin.com/uas/oauth2/accessToken?grant_type=authorization_code&code=https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=123456789&scope=r_basicprofile%r_network%&state=abcdefghi&redirect_uri=http://www.socialinnovationlab.net&redirect_uri=http://www.socialinnovationlab.net&client_id=123456789&client_secret=1212121212

When I try to go to this address I get the error:

{"error":"invalid_request","error_description":"missing required parameters, includes an invalid parameter value, parameter more then once. : client_id"}

any idea where I went wrong?

Thank you

In step a. when you navigate to 

https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=123456789&scope=r_basicprofile%r_network%&state=abcdefghi&redirect_uri=http://www.socialinnovationlab.net

you'll see LinkedIn auth form. Once you submit the form you'll be redirected to 

http://www.socialinnovationlab.net?code=AUTHORIZATION_CODE&state=abcdefghi

Parameter code in the above URL will contain your authorization code. That is the authorization code you'll need to use in code parameter of the URL in step b.
