How do I autostart VBA code when I open a Microsoft Publisher document...

I have written a macro that executes well in Microsoft Publisher (the macro changes a date). What I want to do is have the macro start when I open the document and the date changes.

Does anyone know code or a switch in Publisher that would automatically execute a macro at startup? We searches revealed that macros in Microsoft Word will auto-start with this code:


But I tried this in Publisher and it does not work. Does anyone know of a way?

Thank you,
