Hello and welcome! You didn’t actually post any code. If you are redefining functions inside a loop, you have to make sure those are anonymous functions, as named functions are defined once only.

See this related issue [Same code in if and else blocks, get UndefVarError only on else condition](https://discourse.julialang.org/t/same-code-in-if-and-else-blocks-get-undefvarerror-only-on-else-condition/11611)
