Name error this is driving me insane haha

It's no secret that I'm pretty mediocre at Renpy but I have to say, this recent error is driving me absolutely nuts.

label start:
     $Akechi == 8
     if $ Yusuke == 8: 
         $ Fox = True
     if $ Ryuji == 8: 
         $ Skull == True
     if $ Akechi == 8: 
         $ Crow == True 

     "I think I understand the problem now. But nevertheless, I'd like to give you the opportunity to choose the form your heart takes. You know yourself better than anybody else, self assessment is a valuable tool."
     "What form do you feel your heart is drawn to?"
     if Crow:
         "hi"
     menu:
         "Ryuji option." if Skull :
              e "SKULL"
         "Akechi option" if Crow :
             e "edgelord"
         "Joker option":
             "JOKER"
         "Yusuke option" if Fox:
             "Yusuke"

It keeps returning that Crow isn't defined :')
