Button won't pack into frame

Question

When I try to put my button in a frame, it goes into the Main Window instead of in to the frame. What am I doing wrong? When it shows up, it "packs" underneath the Frames instead of going in to the correct frame.

I tried changing the order, changing the frame names. Nothing is working. Here is my code:

import random
from tkinter import *

#declare variables
computer_options = ["Rock", "Paper", "Scissors"]
user_choice = ""
scoreboard = 0

#functions
def rock_command():
    global computer_choice
    global user_choice
    global scoreboard
    
    computer_choice = random.choice(computer_options)
    user_choice = "Rock"
    
    if computer_choice == "Rock":
        scoreboard = scoreboard
    elif computer_choice == "Scissors":
        scoreboard = scoreboard + 1
    elif computer_choice == "Paper":
        scoreboard = scoreboard - 1
        
def paper_command():
    global computer_choice
    global user_choice
    global scoreboard
    computer_choice = random.choice(computer_options)
    user_choice = "Paper"
    if computer_choice == "Paper":
        scoreboard = scoreboard
    elif computer_choice == "Rock":
        scoreboard = scoreboard + 1
    elif computer_choice == "Scissors":
        scoreboard = scoreboard - 1

def scissors_command():
    global computer_choice
    global user_choice
    global scoreboard
    computer_choice = random.choice(computer_options)
    user_choice = "Scissors"
    if computer_choice == "Scissors":
        scoreboard = scoreboard
    elif computer_choice == "Paper":
        scoreboard = scoreboard + 1
    elif computer_choice == "Rock":
        scoreboard = scoreboard - 1

#set up main window
root = Tk()

#set up frames
title_frame = Frame(root, bg="blue", height=200, width= 600).pack()
image_frame = Frame(root, bg="red", height=200, width= 600).pack()
buttonFrame = Frame(root, bg="green", height=200, width= 600).pack()
score_frame = Frame(root, bg="yellow", height=200, width= 600).pack()

#buttons

paper_button = Button(buttonFrame, text="Paper", command ="paper_command").pack()
#rock_button = Button(buttonFrame, text="Rock", command=rock_command)
#scissors_button = Button(buttonFrame, text="Scissors", command ="scissors_command")


#loop program
root.mainloop()
