Hey everyone, I've just had a look into this. I think the documentation seems pretty clear on what's expected with using the legacy-style parameters https://docs.databricks.com/aws/en/notebooks/legacy-widgets 

@Yourstruly, I appreciate the frustration but that's an out-of-pocket response. Lots of people give up their free time to help build up the community. That's how it works. You've provided only a single post on your profile; it's really hypocritcal to behave in that manner. Be better than that. If things aren't being resolved by the community, go through the appropriate support routes with databricks themselves:

All the best,
BS
