Activate specific sheet when open excel

Hi all,

I would like open a specific worksheet whenever i open my excel irregardless where is my last save.

I have performed the following actions:

1) I have written the following in VBA project:

Private Sub Workbook_Open()

    Worksheets(“Sheet1”).Activate
    Range(“A1”).Select

End Sub

2) I have save it as macro enable worksheet as well.

However, when i open the file, it pop out run time error and unable to jump to the worksheet as written in VBA. I have attached the excel file as well. Please advise.

Thanks & regards,

Kia Boon
