For that I usually use tree statistics, which outputs the branch path (the number in the curly brackets). So you just get the 2nd list item from that *HOW*

Then you use Tree Branch to retrieve that specific branch. *HOW*

Now you can use List Item to get the specific item you are after.

David, thank you for this work

I guess I want a module that spits out branches based on a numeric input like the number 6, or the result of a calculation with an EXPRESSION module.

Then I want to pick cherries from the branch at specific locations with another integer.

i dont want to type curly brackets with array locations in them. Is there a curly bracket module that takes integers as input?

I tried some connections - no luck : /

The immediate goal is to calculate the area of one selected square.

then all the squares - to find the mean, largest and smallest, and count.
