`cij` is only defined in the local scope of the loop but `eval` always evaluates in the global scope. Adding a `global` in front of the `cij=...` should do the trick. But IMO you should refactor your code to not need an eval.

Also, you as a veteran should know how to quote code, please do it: [PSA: how to quote code with backticks](https://discourse.julialang.org/t/psa-how-to-quote-code-with-backticks/7530)
