Hi, I am trying to use a customized Module in the same folder as main.jl. (Julia 0.6v)

I used  
include(“MyModule.jl”)  
using MyModule  
in main.jl. But it returned an error: syntax: missing last argument in “2:” range expression

Could you please help with this? Thank you!

It is impossible to help with no code to look at (see [Please read: make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757)). A qualified guess is that you have something like

```julia
2:

```

somewhere in your code, that should be `2:5` or whatever.

Note that `a[:7]` and `a[2:]` are not valid slicing syntax in Julia: you must either provide both start and end indices or neither, i.e. `a[:]` is allowed to get all indices in a dimension.

Thanks, my bad, I thought the error came from main.jl, when it actually came from the module file.
