Can You Tell What I am Missing?

I am trying to follow this tutorial on Finsweet CMS Filter.

I am trying to make our “Programs & Services” filter with check boxes by main category, location, and maybe more.

The tutorial is different than what I am trying to do so I am not connecting the pieces to make this work.

Here is an image of what I am trying to filter.

Here is my read-only link

Thank you for any advice you can provide.

Hi Robert, for Finsweet questions I’d advice you to go over to Finsweet Slack. Here is an invite: Slack

Thank you

I am sure it is just how I am thinking about the structure of connecting my collections.
