我不明白为什么按下“保存”按钮，放入“ChildName”变量的值是空白？

def AddClassMember():
    global ChildNameEntryVariable
    global AddClassMemberWindow

    AddClassMemberWindow = Tk()

    ChildNameEntryVariable = StringVar()
    ChildNameEntry = Entry(AddClassMemberWindow, textvariable = ChildNameEntryVariable)
    ChildNameEntry.grid(row=2,column=1)
    ChildNameEntrySave = Button(AddClassMemberWindow, text = "save", command = SaveChildName)
    ChildNameEntrySave.grid(row=1,column=1)

def SaveChildName():
    PupilName = ChildNameEntryVariable.get()

    with db:
        cursor.execute(''' INSERT INTO 'Pupil Information' (PupilNames) VALUES (?)''', ([PupilName, ]))

我几个小时以来一直在试图解决这个问题。提前致谢。
