Exporting Variables into a Google Spreadsheet

Thanks for that - I get asked for this all the time. Kate I loved your step by step instructions. Steve I loved your idea of using a javascript trigger instead of having to put something in the published folder and being able to put variables into a google form would be awesome - but I think I would need a few more step by step instructions to be able to make it work.  Do you think you could explain how to do it, for say, the variable scorepercent and a variable for name?  I do get asked for this all the time.
