In multiple examples on this page (forest.regress, StyleCode, etc),
newline-separated parameters are not supported by the playground, throwing error.
Adding a ',' or a ';' (depending on what the 'one-line' grammar requires) will solve the issue.

Thanks for pointing this out. I had the same issue and also resolved it by adding a comma at the end of lines 24 and 25 in the labeled arguments (advanced) section.
