title: CANT GET VALUE FROM ENTRY
body: <p>I'm attempting to develop a registration form, but I can't get the value of the entries because nonetype and return self func are specified.</p>
  <p>I tried entering values into the entries, but nothing worked. Again, we find that understanding some of the features and structure of your code is required before you can make modifications.</p>
