DataviewJS Snippet Showcase

This is great and I would love to implement this, however I can’t get it to work.

In the People note I have added this frontmatter:
tags: [family, friends]
birthday: 2021-08-17

In the Birthdays note I have this frontmatter:
#searchterm:#family or #friends
searchterm: ‘“People”’
duration: 1 year
dateformat: “YYYY-MM-DD”

In this note I have placed the dataviewjs code.
It displays a Dataview query with no results.

Any help would be greatly appreciated.
