This function is useful to summarize fields of a table without table occurency.

it's easy to load the result in a global variable to use it in the solution.

The function can be simplified as shown below.
Oddly, I find the empty string before the second getNth is required to ensure the calc operates properly.

Case( start <= Get(FoundCount) ;

Let([
thisvalue = Case( GetNthRecord ( filterField; start ) = filterItem ;
"" & GetNthRecord ( field ; start ) );

next = ListFound_Conditional ( Field ; start + 1; filterField; filterItem ) ];

List( next; thisValue )
)
)

Oops, that should be list( thisValue; next)

Hi Bruce.
Thanks for your comment.That's another approach, more simple and clear. I did not think to simplify, because my CF was working.
Best regards.

I seem to be having really mixed results with this. It's exactly what I've been looking for, but I'm getting this to list a related field. The results show as expected. But it seems that if I narrow down the search (of the parent table where the list field is), it shows up blank. Any thoughts?
