Path file parameter

Hi guys,

I'd want to parameterize the file path with language M but I can't.

For example:

I have a file Excel in a folder C:\PBI\WORK so in editor I have

let
Origine = Excel.Workbook(File.Contents("C:\PBI\WORK\File_01.xlsx"), null, true),
data_Table = Origine{[Item="data",Kind="Table"]}[Data]
in
data_Table

After, I have created a parameter

Name: PathFile

Type: Text

Current value: C:\PBI\WORK

So, how can I change language M to set the parameter?

Thank you all
