How to change shader normal uvs?

okay, I need that world coordinate uv t$$anonymous$$ng, so I copied the one from the prototyping asset. but I can't quite understand how to write t$$anonymous$$s right, I've searched for hours, but no one seems facing the same problem. I hope you can see it from the script, the error is in the line:

 o.Normal = UnpackNormal(tex2);

theres the full scipt/shader:

 Shader "Custom/NewSurfaceShader1" {
     Properties {
         _Color ("Color", Color) = (1,1,1,1)
         _MainTex ("Albedo (RGB)", 2D) = "w$$anonymous$$te" {}
         _Glossiness ("Smoothness", Range(0,1)) = 0.5
         _Metallic ("Metallic", Range(0,1)) = 0.0
         _BumpMap("Bumpmap", 2D) = "bump" {}
         _BaseScale("Base Tiling", Vector) = (1,1,1,0)
