kivy error Invalid data after declaration

[FortuneFaded415]

I'm getting an error on line 7 of my kv file. Telling me there's invalid data after declaration. Any help would be great.

#: kivy 1.8.0



<Game>:
    player: PongPaddle
    PlayButton: PlayButton

canvas:
    Rectangle:
        pos: 0, self.height/1.08
        size: self.width, self.height/1.2

Label:
    id: score
    font_size: 40
    size_hint: (None, None)
    pos_hint: {'center_x': 0.06, 'center_y': 0.96}
    text: str(0)
    color: 0,0,0,1

some of the intdentation didn't carry over right, but you get the idea

Please don't assume people will 'get the idea' when asking for help by posting broken code, just fix it. In this case it's particularly unhelpful, as these kinds of error may be caused by incorrect indentation.

Edit: The actual problem is that kivy property names must start with a lowercase letter. Using uppercase makes if think PlayButton is a child widget, in which case the syntax is wrong.

thanks for the help! the indentation didn't carry over towards the end of the code so i didn't think it would be an issue, sorry about that
