I am attempting to get a startup screen with a button to input zipcode, price min/max. I am getting nothing popping up, and an error output of ...
File "C:\Users\hanna\anaconda3\envs\spyder-cf\lib\site-packages\kivy\lang\parser.py", line 756, in parse_level
if current_property[:3] == 'on_':
TypeError: 'NoneType' object is not subscriptable
My code is not compiling, due to some errors (presumably with syntax or the default parameters of the code). Anyone who has worked with Kivy before, please hit me up!

How do I make the stacklayout code showup with the kv file code? Or at least make the stacklayout part of the screen.
Right now the only option I have is either take the screen as output or the stack layout as output.
Replacing the def build(self) inside the class FourthWindow(Screen) will show the whole application. The code inside the def build(self) also works but they do not work together.
I am new to kivy and object oriented programming so I do not know much about this topic so I could be missing something really basic.
I am trying to add an action bar on top in the first screen of my project. I tried using screenmanager widget and sending the action bar as it's children like how to manage/get both of the screens. At first I tried just adding the action bar code in root.widget in the first screen, but they are showing the class for this as an invalid class.
How to add both of them? Also I can't show the buttons from top to bottom even though I added orientation : 'vertical'

I tried searching solution on the internet, but after 3 hours of searching I couldn't come up whith any answer.
All my program works up-to a point and I'm road blocked by it.
My program loads some starter screens in the main app.
Based on user input the program loads a completely different sub app.
Problem occurs when trying to change screens in the loaded sub app

The problem:
When clicking the stats button on the home screen in executew the WarriorStats screen named 'WStats' should be loaded, but I get the error "no screen with name 'WStats'"
Answer that I figured out on my own
class HomeScreen(Screen):

self.manager.current = "WStats"
And in executew:
<HomeScreen>
Button:

on_release: root.switch()
My application is simple, the ScreenTwo is showing a form 'Parametreur' with various options to be entered.
What I'm trying to do is to set a 'save' button at the end of this form that will register into a list called 'resultat' all the options furfilled so far leaving '0' in the empty inputs.
The global variable 'resultat' would look like this ['blabla','15/06/2018','31/12/1999','6'].

Where and How should I set my global variable 'resultat' (which is a list)?
I've solved my problem but I still don't understand how does it work. Setting a variable is Kivy doesn't need to set it in the Python code. But how do Kivy and Python know about its type? Right now, it works as a list without me defining it such as (I intended it to be a list anyway).
How could I set a variable as tuple for example?
