Not to be that one person, but there shouldn't be a comma between 'are you sure about that" It's a complete sentence, if you were to say "Are you sure?" That would be a complete sentence, but since you added on a dependent clause after you made the sentence incorrect. It's simply "Are you sure about that?" Sorry lol.
