Me too, but while you're away, you could ponder on this question :) I wasn't aware that spreadsheet editors also could edit the script. Isn't that a security risk? If I let "anyone with the link" edit my spreadsheet, they can apparently also do anything to the script (like DDOSing something). What do you usually do, when you want to demonstrate something in a spreadsheet?
@VidarS.Ramdal I face those problems as well. Nowadays I set the option to "view" rather then to "edit". People still can make a copy and explore the solution this way.....
