Maybe this will make the issue I’m having a little clearer. Here is a post I worked on last year for a bit that was throwing the error in questions.
When my loops become too large, I get a bracket nesting level error. Granted, in that old case, I was looping across a bunch of potentials as well, but I think the issue will remain the same.
Noted on the vectorizing as well, will be more aware of that going forwards.
