You need to run the pre-commit checks to format the notebook and run checks on the meta.toml (I see that it's missing the icon field). See https://github.com/singlestore-labs/spaces-notebooks/blob/master/CONTRIBUTING.md.

As for the notebook itself:

1. Add a paragraph or two at the top describing what the notebook does.

2. You should use uppercase for all SQL keywords. The casing is inconsistent.

3. Don't use use time_series. See one of the getting started notebooks that have a note about selecting time_series from the database selector in the notebook interface. This ensures that all new connections use that database.

4. I think you are missing some %%sqls is some cells. See In[38] and a few after that one.

5. Make sure you are selecting Markdown as the cell type if typing documentation. I see a few blocks of documentation that are in code cells.
