Hi @Jason_Burke - I think the problem here is that you are literally searching for the string “rec6CS1RqOjcYLwXf” in the ARRAYJOIN value, but, I assume, you want to search for a field value associated with record “rec6CS1RqOjcYLwXf”.
(I’m also assuming that your ARRAYJOIN is something like this:
To make it work your formula should read something like:
or if the search term is dynamic, then do something like:
let searchTerm = [Get the dynamic value here from a record, table, etc]
