Copy/paste from another workbook

Question

It is a simple task, but I don't know why it is not working…

This is my code :

Dim chemin As String
Workbooks.Open ("Z:\ext_Workbook.xlsx") 
Sheets("produits").Activate
Sheets("produits").Range("A1:CZ500").Copy 

ThisWorkbook.Activate
Sheets("STT").Select
ActiveSheet.Range("A1").Select
ActiveSheet.Paste

Application.DisplayAlerts = False
Workbooks("ext_Workbook.xlsx").Close

The run stop at the line :

 Sheets("STT").Select

But I verified, and there is a sheet named STT , with the same spelling

Answer 1

The below should work for you.

Dim SourceWBK As Workbook, DestinationWBK As Workbook

Set SourceWBK = Workbooks.Open("Z:\ext_Workbook.xlsx")
Set DestinationWBK = ThisWorkbook

SourceWBK.Worksheets("produits").Range("A1:CZ500").Copy
DestinationWBK.Worksheets("STT").Range("A1:CZ500").PasteSpecial Paste:=xlPasteAll
Application.CutCopyMode = False

Application.DisplayAlerts = False
SourceWBK.Close False
