Omit Featured Entry from loop of entries with additional omissions
My variable wasn't outputting the id and it wasn't being pulled into my omitIds variable

{% set featuredIds = entry.featuredEntry.first.id %}

{% set omitIds = 'and, not ' ~ taggedEntries|join(', not ') ~ allEntries|join(', not ' ~ featuredIds) %}


Adding .first.id to my entry.featuredEntry outputs the correct id.
Then removed featuredIds from the ', not ' in omitIds and added ~ featuredIds pulls in the correct id and omits it from the list.

Feel free to edit as I'm sure I'm not explaining this correctly.
