Pipe opening auto putting

Hi, i have a problem. A few months before i made my first dynamo to put openings families on pipes. Now i want to improve my script(wall orientation, and dimmensions). I rebuild him in the way from Aussie Bim Guru but using linked model walls Create Wall Penetrations using Dynamo! - YouTube
But nothing wants to work. I think this is something with lists but i tryed all types and configurations, few roads and still i am at the start point… Now after two evenings of fighting i need to surrender and ask the question on forum. Do you know where i makes the mistake? Thanks in advance!
