Can’t post on a subreddit

I’m trying to post on relationshipadvice but it’s not letting me. I have a throwaway account, and I have everything filled out, title and text, but the post button is greyed out.

I have a message appearing telling me that I need to put a question, and it can’t be yes or no. I’ve added my question, it’s not a yes or no question, and yet still nothing.

Why isn’t it working?
