Gummie asked me to send this - [https://www.gumloop.com/pipeline?workbook\_id=6LC4Wxbw4Gn8LkhKYiFWAq&tab=1&run\_id=PjVLQZ3WtftgoHpXzTo8FD](https://www.gumloop.com/pipeline?workbook_id=6LC4Wxbw4Gn8LkhKYiFWAq&tab=1&run_id=PjVLQZ3WtftgoHpXzTo8FD)

hey! I see the issue!
You’re trimming those two paths properly but then sending a full length list right down the middle with no trimming.

If you trim the middle path it’ll work!
