Hi I have grouped points by its z value. I’am able to pull the result that I want from index of one sublist, but how can I loop thru rest of the sublist to get the result? any suggestion? Thanks Works: ![sublist works](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/b/f/bfa3af3bc40e697cf84c7824041e297c895f4f6b.JPG) Doesn’t work: ![sublist not work](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/f/e/fe109cca988d8ab06dba9653c615468f76e1b856.JPG) ---

I think you just need to put `0..3` in parenthesis. `(0..3)` But really you should be able to do it with levels. ---

You just want the first list of every sublist right? ![image](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/3X/6/f/6f5725dfcf758c17005a79edccfba9e91f3a6a8a.png) ---

I hope this image will explain what I want: ![group](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/a/d/adf9a1b1aac0f52afdef6c21e01fa8c0dce2f97d.JPG) ---

Then you need to go to the second level. You might also want to keep list structure depending on what you’re doing next. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/3/d/3d5b1d3dccf854a936700e25700c96fb6069968d.png) ---

Thanks a lot Nick, It works. Is there any way to use level syntax in the code block? ---

You could try setting lacing to longest, but that can be dicey. List.map and a series of functions could also do the trick. Levels is a lot easier and faster though. ---

When in doubt, right click and use Node to Code to see the Design Script syntax. ---
