You are missing square brackets around findall.

```julia
kody5[1][findall(rx,kody5[1])] 

```

Sorry but not works

```julia
julia> kody5[1][findall(rx,kody5[1])]
ERROR: MethodError: no method matching getindex(::String, ::Array{UnitRange{Int64},1})

Works like this, with spcjal

```julia
julia> kody5[1][findall(rx,kody5[1])[]]
"00-028"

```

You are using `findall`, `findall` will always return a vector with all ranges, by using `[]` you are now getting only the first range, are you sure this is what you want? If this is what you want you should just use `findfirst` instead of `findall`.

Yes, sorry, it’s an array so you need to extract an element.
