Mod Constructor Help - Rival Traits

I needed some help working with the trait creator in the Mod Construction V4, I want to make it so I have these opposite traits. Like fandoms that dislike each other, where if a sim has the first trait it will dislike the second sim because they have the opposite trait, vice versa. I was hoping I could find someone to help. Thanks in advance! (I hope I put this question in the right place lol.)
