Hi @TheuriKingori
You didn't attach your form so we don't even know what kind of error you get but:
- if you want to randomize choices in select questions you need to use randomize() function
- if you want to randomize the order of questions here you can find a sample form on how to do that: https://docs.google.com/spreadsheets/d/11LEhyjkRWryTKKfmlyTMWOUkKLDRnY9JDAOqgCzEE2M/edit#gid=0
If it's not enough to solve your problem please attach your xls form.
