The letter A that's being checked in my multiple choice quiz works perfectly, but I'm getting this runtime error. Please help?

Hi! I'm quite new to MIT app inventor, and currently, I'm working on an app that lets you take a multiple-choice type of quiz-- it's for a project I'm working on for school. I'm having a pretty difficult time figuring out how to fix this sort of runtime error, and I'm kind of panicking at the moment since this project is kind of due tomorrow morning, so it would be greatly appreciated on my end if anyone could help me out with this!! Thank you in advance! :')

Check these blocks; .checked should only be provided a boolean value (which you have done properly in the same program)
