It looks like you have probably copied old solutions from the Internet. If so, that is a) cheating and b) doesn’t work, because the course assignments were significantly rewritten in April of 2021.

I think you should do as Nobu suggests and start with a clean notebook and then implement your own solutions based on the instructions in the notebook. There is a topic on the DLS FAQ Thread about how to get a clean copy of any of the notebooks.
