Sorry I was on Holiday. So I am just now getting back to this.
So first I want to say I didn’t write the code. I edited it from code that @bradleycox255 had on the 2d towards camera post.
I guess I don’t understand why I didn’t get any errors with any of my devices or pc zapper app?
Both @bradleycox255 zpp file and my edited code worked. So why did @eliaskhs get NaN errors?
