Hello, good morning. I’m having an issue building a custom module, that I’ll use to automate some things for machine learning. There are functions in my module that cant find another modules present in the environtment:

```julia
using GLM, DataFrames, CSV; 
using StatsModels: TableRegressionModel, StatisticalModel;

module SampleModule
	export testfunction;
	export IntPoint;
	export r2;
	
	struct IntPoint
		x::Int64
		y::Int64
	end

	"""
		testfunction()

	This function does nothing.

	# This is a tile
	## This is a subtitle
	### This is a section
	"""
	function testfunction()
		println("this is a simple function");
	end

	function r2(model)::Float64
		beta0, beta1 = GLM.coef(model)
	end
end

```

And when I will use it in the environment as:

```julia
julia> include("sample.jl")
julia> using .SampleModule

```

I got the following error:

```julia
julia> SampleModule.r2(model)
ERROR: UndefVarError: GLM not defined
Stacktrace:
 [1] r2(model::TableRegressionModel{GeneralizedLinearModel{GLM.GlmResp{Vector{Float64}, Binomial{Float64}, ProbitLink}, GLM.DensePredChol{Float64, LinearAlgebra.CholeskyPivoted{Float64, Matrix{Float64}, Vector{Int64}}}}, Matrix{Float64}})
   @ Main.SampleModule C:\Users\jcbri\Documents\Workspace\julia\explore\sample.jl:28
 [2] top-level scope
   @ REPL[50]:1

```

What I’m missing?

Got it here. It needs to be included inside the module declararion

```julia-auto
...
module X
using GLM, DataFrames, CSV; 
using StatsModels: TableRegressionModel, StatisticalModel;
...
end

```
