There is a minor glitch in your code at Line 10. Should be const issuesString = issues.join (', '); and you have const issuesString = issues.join ('', ' '); But that won't stop it from working.
What do you mean when you say it's not working? Are you getting an error message in the script compiler, or when you save the xlsx sheet, or something else"
What happens when you test your code? Click the "fx" button on the scripts page, then copy in one or two of your choices from the worksheet, separated by a comma ",". Then click the execute button ">".
I've tried to replicate the sheet and code that you are using, and it works fine. I've attached the files below. Try those and see if you can get them to work, then you can use that as the basis for your own suvey.
If you upload your xlsx sheet and your js code, I'll try it at my end and see if it works. That might be the fastest option.
Cheers.
