This error can be puzzling, especially for beginners. In this post, we’ll break down why this error occurs and how to fix it effectively.

Understanding the Problem

When you create a form using Tkinter, you typically utilize different widget types such as Entry, Label, Button, and more. The Entry widget allows users to input text, such as names or emails.

However, there's a crucial aspect to consider: how you assign values to these variable names while creating your input fields.
