I believe it’s a known limitation by the weweb team, based on a previous post. [How can I filter by date from a collection where the date is part of an addon from Xano - #3 by MichaelLovell](https://community.weweb.io/t/how-can-i-filter-by-date-from-a-collection-where-the-date-is-part-of-an-addon-from-xano/2311/3)

Not seeing the data structure but making some assumptions, switch to the javascript formula and try something along the lines of this…

```auto
// Access the global variable containing the data Family
const items = collections['your-collection-id...de439c6947c9']

// Filter the items based on the 'family_member.id' property
const filteredItems = items.filter(item => {
    return item.family_member.id === user_id;
  });

  // Return the filtered items
return filteredItems;

```
