Hello @berrysweet ,

I am checking your notebook.
I see in many functions you haven’t replaced the “None” with correct parameters and values.

That’s why you are getting NoneType errors.

You need to code between the block :


You need to replace the “None” under every graded functions with appropriate parameters/values/variables/etc.
Sometimes you may also need to write code of your own within the start code...end code block.
