Welcome message box

[esherr77]

hi guys

been trying the following in order to get a nice looking welcome message

Sub Auto_Open()
msgbox "Welcome to Excel"
End Sub

Yet it just doesnt open up whenever I open the file.

Any suggestion is well accepted.

Thanks in advance.

In ThisWorkbook module

Private Sub Workbook_Open()
MsgBox "Welcome to Excel"
End Sub
