cross domain tracking GA

been having trouble with cross domain tracking issues - turns out that the documentation on the google site was wrong... classic. This was the response from the big G:

Hello Bill,

Thank you for your email. We greatly appreciate any feedback or suggestions for ways we can improve Google Analytics.

Please note that I have informed the concerned team about the error in the documentation. As you mentioned, the article is incorrect:

<a href="https://www.secondsite.com/?login=parameters"
onclick="_gaq.push(['_link', 'http://www.firstsite.com']); return false;">Login Now</a>

It should be:

<a href="https://www.secondsite.com/?login=parameters"
onclick="_gaq.push(['_link',
'https://www.secondsite.com/?login=parameters']); return false;">Login Now</a>

Thanks for bringing this to our attention. Please note that this documentation will soon be edited.

If you have additional questions, please visit our Help Center at http://adwords.google.com/support/aw/, where you'll find answers to many frequently asked questions. We look forward to providing you with the most effective advertising available.

Sincerely,
