Creating a leaderboard with Captivate & Google Docs

I was wondering if anyone knew what changes you'd need to make to get the solution in the link below working for Captivate?

They have said they'll be releasing a Captivate version soon. But wondered if any forums members familiar with Javascript could see if it was just a few tweaks that would need changing?
