Python 名称错误：名称'；ChildFirstBox3'；未定义-尝试#1-7时出现相同错误，但对8正常工作

我试图弄明白为什么我的代码在这里运行时会出错

    def Scroll():
global ChildScroll
global text_area
TESTSCROLL()
# Title Label
ChildScroll = Label(AppWindow, text="Review Info",
                    font=("Times New Roman", 15),background='green',
                    foreground="white")
ChildScroll.place(relx=0.5, rely=0.03)

# Creating scrolled text area
# widget with Read only by
# disabling the state
text_area = st.ScrolledText(AppWindow, width=15,height=8,
                            font=("Ariel",10))

text_area.place(relx=0.5, rely=0.1, relheight=.4, relwidth=.3)
# Inserting Text which is read only
# IF statement + Batman functions
text_area.insert(tk.INSERT, TextForReview)

# Making the text read only
text_area.configure(state='disabled')
#ForScrollText()

在我的程序开始时，要求用户填写他们的信息并键入他们的子女数量（1-8），然后我的代码只填充输入框以填写有关他们子女的信息。完成此操作后，他们单击一个名为review的按钮，它将显示用户键入的信息。我正在用尽屏幕空间，试图将所有信息放入页面中，因此我查看了如何添加滚动小部件以提供帮助。当输入#8时，用户键入的所有信息都会完美地显示在该查看页面中，并且滚动条工作正常，但是如果用户尝试输入除8以外的任何数字（因此为1-7），我会在标题中列出错误。我做错什么了吗
