Thanks (from the future responders :wink: ) for the changes to colors and freezing.

About the Free and Open Source:
1 way you could introduce it is by copying the values that are currently there in the "Free and Open Source" row.
So in other words:
Changing "Free and Open Source" to just "Free".
Adding a row underneath with "Open Source".
And If the field currently has a value for "Free and Open Source" of say 2. Both fields ("Free" and "Open Source") will read 2.
Then the respondent could go back and change the value (of they want). And future respondents can fill it out straight away.

It's not ideal, but especially with the knowledge that if the first 10 respondents have both fields the same, they probably didn't change it after the change to the sheet. This would still be very valuable information for Laurent I think.
