Odds error

I'm getting an error code which I don't understand pls help

At the moment, when ancestry is dragonborn the skin color in the image layer combiner should be any color of the rainbow, and with any other ancestry it should be limited. I've tried to mark the variables with ^[r.species != "dragonborn"] etc but it's telling me that's not an allowed odds

the section is marked with //RELEVANT SECTION OF CODE//

Thank you in advance :)
