Set a cell's default value when opening a file

Hi there,

I have a workbook with cell A1 containing a drop-down list box. Users can choose how they want to "view" project data by changing this list box. Users can choose from "Project", "Phase 1", "Phase 2", etc.

What I would like to do is to make sure that each time a file is opened, the user first views the data from the "Project" level.

Is there a way for me to change cell A1 to "Project" every time I open my workbook?

Thanks,

JF
