Cool idea! One suggestion I have is to offer Copper as an option for cu. Also, I'm not quite sure how to do it myself, but maybe you should make it so it accepts each word separately? I see it on some quizzes.
Thanks! I was proud of this quiz. More of these to come, for sure. Looks like we are in the same boat! Not quite sure how to edit the quiz so that it will accept cubic and copper separately, but for now, I added copper as a type-in. I will investigate the situation, probably even ask on Jetpunk's subreddit, and report back.
It is now finally fixed! Thanks so much for your suggestion, as it helps better my quizzes! Jerry928 also helped me out on the subreddit (as I'm sure you already saw) with merging the cells.
Thanks for the mention! A couple of other bits of feedback: Also accept "organisation"? You can achieve that using the type-in box and choose "Regex" then type in ^NORTHATLANTICTREATYORGANI[SZ]ATION (the ^ means "starts with", and where 2 or more letters are bracketed, either will work). Thus ^S[IOU]N will accept sin, son or sun, and ^S[IOU]+N will accept sin, son, sun, sion, soon, and even soiuiuioiuiiiiiiioin. But S[IOU]N without the leading ^ accepts anything as long as it contains son, sin or sun, for example Anderson. Also, when I typed in copper, it gave me cubic as well! To make people choose both, one answer at a time, you'll need to have copper as one answer, and cubic as the other. Finally "Lib" can also mean Liberal or Libertarian, and "co" can mean Company.
You're welcome! Thank you so much for the NATO type-in feedback and other words that can be abbreviated as Lib. and co. It may have taken a while for me to figure it out, but I probably never would have without your help. Please let me know if you notice anything else, as you definitely helped better this quiz!
