Having trouble with user input in tkinter

Question

I am working on a program for class and am having trouble with user input. This is what I have, can someone help me figure out what I am doing wrong? All of the buttons work (this is only part of the code), but the user input area for menu3A doesn't seem to accept the user input. It tells me that variable1 is undefined.

Module 1:

from tkinter import *
from tkinter import ttk
import functions
import finance

def donothing():
   filewin = Toplevel(root)
   button = Button(filewin, text="Do nothing button")
   button.pack()
 
# Menu 1 - opening menu

def menu1():
    filewin = Toplevel(root)
    button1 = Button(filewin, text="Use your own CSV Data", command = menu3A)
    button1.pack()
    button2 = Button(filewin, text="Use Data Included in program", command = menu2)
    button2.pack()

# Menu 2 - Menu 2 is only used if Data from Menu1 specifies program data used
def menu2():
    FileName = ''
    filewin = Toplevel(root)
    Label(root, text="Enter the ticker symbol for your chosen stock or type Back to go back: ").grid(row=0, sticky=W)  #label
    Entry(root, textvariable = FileName).grid(row=0, column=1, sticky=E) #entry textbox

    WSignUp = Button(root, text="Enter", command=functions.getvalue2).grid(row=3, column=0, sticky=W) #button

# Menu 3A - loading CSV File - only used if Data from Menu1 specifies user wishes to load CSV
    variable1=StringVar()

    ttk.Entry(root, width=7, textvariable=variable1).grid(column=2, row=1)

    ttk.Label(root, text="Enter Filename: ").grid(column=1, row=1)

    ttk.Button(root, text="Enter", command=functions.getvalue1()).grid(column=2, row=13)

root = Tk()
root.title('Rachels Stocks Python Program')
menubar = Menu(root)
filemenu = Menu(menubar, tearoff=0)
filemenu.add_command(label="New", command=menu1)

filemenu.add_separator()

filemenu.add_command(label="Exit", command=root.quit)
menubar.add_cascade(label="File", menu=filemenu)
editmenu = Menu(menubar, tearoff=0)
editmenu.add_command(label="Undo", command=donothing)

editmenu.add_separator()

editmenu.add_command(label="Cut", command=donothing)
editmenu.add_command(label="Copy", command=donothing)
editmenu.add_command(label="Paste", command=donothing)
editmenu.add_command(label="Delete", command=donothing)
editmenu.add_command(label="Select All", command=donothing)

menubar.add_cascade(label="Edit", menu=editmenu)
helpmenu = Menu(menubar, tearoff=0)
helpmenu.add_command(label="Help Index", command=donothing)
helpmenu.add_command(label="About...", command=donothing)
menubar.add_cascade(label="Help", menu=helpmenu)

root.config(menu=menubar)

root.mainloop()

Module 2:

import finance


#Function that menu 3A uses to print and use CSV filename
def getvalue1():
    FileName = variable1.get()
    print(f"Filename entered is: {FileName}")
    finance.CSV_Finance_Tool(FileName)

If I try to do this:

WSignUp = Button(root, text="Enter", command=functions.getvalue2(variable1)).grid(row=3, column=0, sticky=W) #button

Then it automatically seems to pass the empty variable onto CSV_Finance_Tool and I am getting the file exception response of file not found. It doesn't wait for the user input.

please [edit] your question to include a [mre], the complete error traceback (starting from word "Traceback") and elaborate a bit more on the issue — Matiiss, Nov 02 '21 at 15:13
`variable1` is not defined in that file pretty clearly, do you see anywhere in the `finance` module that `variable1` is defined? I would suggest that you pass whatever `variable1` returns as an argument to `getvalue1` function — Matiiss, Nov 02 '21 at 15:17
I have tried that but then it goes straight into the CSV_Finance_Tool and I get the error that the file is not found because it is sending an empty variable. — Rachel Liane, Nov 02 '21 at 15:19
