Problem with Multiple Choices Template

I am running through a problem with multiple choices template. I inserted a multiple choices template and it showed the error message when I previewed it. I didn't have this issue before. I wonder if I did something wrong (I don't think I did anything different today) or if it's something wrong with the application. Please see the attached error message.
