Correctness Check Problem on the Summary Page

I created a slide that I would like to replicate for student practice. However, I am not receiving a checkmark in preview.

I have a “correct” statement for each of my components. When I finish the slide, I receive an “x.”

Would anyone be willing to help me?

I figured it out. I was not typing the latex correctly.
