[pygame] Inventory items not working

[SheeppOSU]

I decided to start it from scratch. I fro one wanted your opinion on how I am starting and I also need to know how to fix one of my problems. Originally I had the login and two text boxes. The button was only detecting clicks at certain times though so I separated it to give it a bigger range of detection. It still won't work though.
Here is the full code if you could take a quick scan and grade it

import pygame, random, os, sys
from functools import partial
from pathlib import Path
from DestinationFunc import Screen_Display as SD, Button as BT, TextBox as TB

pygame.init()

width = 800
height = 800
fps = 80

Screen = pygame.display.set_mode((width, height))
clock = pygame.time.Clock()

UserData = {'Sheepposu' : {'password' : 'password'}}

class Player():
    def __init__():
        pass


class Enemy():
    def __init__():
        pass


def SignIn():
    #Intro
    sizeVar = 1
    OrganizationTup = (((205, 0, 0), 405, 295), ((215, 0, 0), 404, 296), ((225, 0, 0), 403, 297),
                       ((235, 0, 0), 402, 298), ((245, 0, 0), 401, 299), ((255, 0, 0), 400, 300))
    while sizeVar < 120:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                EndGame(True)
        sizeVar += 1
        Screen.fill((0, 0, 255))
        for x in OrganizationTup:
            SD.message_display(Screen, 'Destination', sizeVar, x[0], x[1], x[2])
        pygame.display.update()
        clock.tick(fps)

        password = TB((200, 650, 400, 100), 'Type Password', 50, (0, 0, 255))
        login = BT((650, 550, 100, 50), 'Log In', 40, (0, 0, 255))

            username.start(Screen, (255, 0, 0), 20)
            password.start(Screen, (255, 0, 0), 20)
            if username.text != '' and password.text != '':
                break

        UserName = username.text
        PassWord = password.text
        for name in UserData:
            if UserName.lower() == name.lower():
                if PassWord == UserData[name]['password']:
                    Logging = False
                else:

Button Code -

for event in pygame.event.get():
            clicked = pygame.mouse.get_pressed()
            if event.type == pygame.MOUSEBUTTONDOWN and clicked[0] == 1 and pygame.Rect((200, 650, 400, 100)).collidepoint(pygame.mouse.get_pos()):
                #code
