Question

in line 7 it throws the error:

:kivy 1.0.9

: orientation: 'vertical' spacing: 10

BoxLayout:
    size_hint_y= None
    height: 50
    Label:
        text: 'Account Control'
        bold: True
        size_hint_x=.9
    Button:
         text: 'x'
         size_hint_x= 1

6: BoxLayout:

7: size_hint_y= None 8: height: 50 9: Label: ... Invalid property name

Answer 1

This usually indicates a syntax error messing up the property name parsing. In this case, your error is on the line you picked out: size_hint_x= 1 should be size_hint_x: 1 .
