I have this struct created in a file:

 ![struct_env](https://global.discourse-cdn.com/julialang/original/3X/6/6/662d1387894afbc45fb8803565bccd3a687d767f.png)

I’m including it on another file using:

 ![imports_data_gen](https://global.discourse-cdn.com/julialang/original/3X/9/2/92e1a1c7824a89b247e94c762a5b6a794aa37355.png)

But, when a try to call the constructor of the struct inside of a function like this:

 ![declaring_inside_function](https://global.discourse-cdn.com/julialang/original/3X/d/a/da1ace70ed3cecf336f669c96c57f2e8a61b8729.png)

I get this error:

```julia
ERROR: LoadError: UndefVarError: e not defined
Stacktrace:
 [1] generate_env()
   @ Main ~/path/to/file/data_gen.jl:161
 [2] top-level scope
   @ ~/path/to/file/data_gen.jl:167
in expression starting at /path/to/file/data_gen.jl:167

```

Could someone help me?

What is the last `e` in

```julia
e = Environment(dfp, ... , e)
---------------------------^

```

Ops… I’m sorry. I’ve been working for so many hours that I couldn’t realize. 😵‍💫  
Need to sleep…

Thank you very much for your help!
