Also, you may be forgetting to put "ee" in the third column for wrong answers.
Ex.:
(1st column)------------(2nd column)------------------(3rd column)--
Is it nighttime?---------Yes!/y----------------------------It is 10:55 PM.
Is it nighttime?---------The answer was yes!/n-----ee----------------
Checked boxes should be:
Accept single character answers
Hide 3rd column until answered
Bonus/Hidden answers become wrong answers
Force answers in order
(Optional: Randomize order of answers)
