Invalid data after declaration

I am trying to make a sort of personal vocabulary journal, I am new to python and kivy. My code is giving an error, i have checked it several times but still not working.It says invalid data after declaration I have checked for any possible error(which i know). I would appreciate any kind of help.
here is my code-

import kivy
kivy.require('1.10.0')

from kivy.uix.stacklayout import StackLayout
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.label import Label 
from kivy.app import App 
from kivy.uix.popup import Popup   
from kivy.uix.screenmanager import ScreenManager, Screen 
from kivy.lang import Builder 
from kivy.properties import ObjectProperty

import json

Builder.load_file('VocabularyJournal.kv')

class MenuPage(Screen, StackLayout):
    pass

class WordInsertPage(Screen,FloatLayout):
    pass

class NewWordPage(Screen,StackLayout):
    word_box = ObjectProperty()
    meaning_box = ObjectProperty()
    Synonym_box = ObjectProperty()
    Ant_box = ObjectProperty()
    sentence_box = ObjectProperty()
    def input_data(self):
        data={}

        m=self.word_box.text
        data[m]={}
        data[m]['meaning']=self.meaning_box.text
        data[m]['synonym']=self.Synonym_box.text
        data[m]['antonym']=self.Ant_box.text
        data[m]['sentence']=self.sentence_box.text

    def saving_data(self):
        with open('vocab_new_word_page.txt','w') as of:
        json.dump(data,of)


class FlashCard(Screen):
    pass

class WordGroups(Screen):
    pass

sm=ScreenManager()
sm.add_widget(MenuPage(name='menu'))
sm.add_widget(WordInsertPage(name='insertword'))
sm.add_widget(NewWordPage(name='newword')) 
sm.add_widget(FlashCard(name='flashcard'))
sm.add_widget(WordGroups(name='wordgroup'))

class VocabularyJournalApp(App):
    def build(self):
    return sm

object = VocabularyJournalApp()
object.run()

and here is the kv file-

According to the docs:

Widget names should start with upper case letters while property names should start with lower case ones. Following the PEP8 Naming Conventions is encouraged.

So in your case the solution is to change the first letter of the properties to lowercase:

.py

synonym_box = ObjectProperty()
ant_box = ObjectProperty()

.kv

meaning_box: meaning_input
synonym_box: Synonym_input
