J.Query Multi reference cms nesting on static page

I feel like this is going to be super simple and obvious :roll_eyes:

I have been searching for a better solution for multiple nested cms lists on a static page, as the Finsweet attributes is a bit too clunky to hand off to a client to manage. It requires a collection to be set up AND apparently plain text too, it’s too much work to manage.

So, I found the seemingly perfect solution in Philipp Roth’s J.Query fix.

But I’m a low-code dummy and i can’t get it to work.

The training page will have 3 nested collections within the main collection:
Dates for the 1st year of a course
Dates for the 2nd year of a course

I have styled them on their respective template pages and in theory, it’s just a matter of fetching them.

But I can’t get them to work :confused:

Please help!
