All+F11 to enter VB editor. Double-click ThisWorkbook.

Paste the following:

Private Sub Workbook_Open()
<Your Code Here
End Sub


I believe the code will run once the password is entered.

What code do I need to run a macro when a file is opened? The sub name is
PNL. Also, this file is password protected. Will that affect anything?

Thanks
