^Also important here is to turn off ALL filtering props on the Tile viz.

Oh, great, thank you! And I've figured out that as a workaround/hack I can use the Title of a Tile viz without data to display interpolated @parameter() values. An upvote on this idea should be considered an upvote for supporting @parameter() references in a Text Box.

Thanks, Gabby. I will take a look at Parameter values. Meta question to the Community: I got a notification that "Voting for this idea is closed." Why is that, when "Variable Interpolation in Text Boxes" is right in the title and Gabby agreed "It does not currenly support Textbox." Do I need to submit a more finely-tuned…
