Database Submit Entry Syntax Error

[Melford]

Thanks for the feedback @Denni, I had asked a question before as I'm trying to learn as much as possible from integrating a database via GUI for an assignment in like May or something, just want practice in for it so any assistance would help my understand a lot but also don't get mad cause I'm quite frankly awful hence why I'm cramming some practice in now. Now the disclaimers over with hopefully I can ask some dumb questions without upsetting anybody :D

Do I need to define the get attribute?

Error:
Exception in Tkinter callback
Traceback (most recent call last):
