Hi Michaela,
Thanks for explaining the behaviour, I managed to fix the function and now it passes. I was joining on more columns than required. I see why you don’t need to join on lapId, but does it not make sense to join on date/session? Any default values from another date or session don’t seem like they would be particularly meaningful to me. Or is it expected to do any filtering before using the function, and therefore it’s not an issue? This doesn’t matter for the capstone, it’s more out of curiosity and what might be expected in practice.
