Hi trying to run a small variation of the code here: https://docs.streamlit.io/develop/concepts/multipage-apps/page-and-navigation

I am getting the AttributeError. Not sure where I am going wrong.

  1. Are you running your app locally or is it deployed? Local
  2. If your app is deployed: No
  3. Share the link to your app’s public GitHub repository (including a requirements file).
  4. Share the full text of the error message (not a screenshot).:
