Oh, ok. My mistake. For some reason, I thought that responses.xls would keep the changed values from session to session. That's cool. It looks like we may have decided to simply have a preliminary practice session before the video presentations, so we can have the instructions there, and there isn't any real need for the responses.xls solution.

I may try it out, anyway, just to see if it works like I think it should. Just for kicks, if nothing else.

Thanks!
