Is the AF parameter one of the items you have checked to log? If so, uncheck it and try again doing exactly what you are doing. Even though it will now be unchecked, click it and start the logging. Then look at the log....I think I had an issue like this when I first started. Now that I think about it...does it tell you that you might have too many things checked?? I think that was my problem...I had too many parameters being logged and i think it would only pull up one. Try like 10 and no more...this is about the max I log. Or hell, try like only 4 and see what happens.
As far as the google doc, just set the permission to "anyone who has the link".
