I've been sent an Excel Workbook and an add in. I'm told that when used
together, several additional menu options are available to the user.

1) Is there an obvious place where the add-in should be saved on my system?
2) How do you add menu options with an add-in
3) Apparently, the menu option is only displayed when one workbook is used.
How is this set up.

I don't need code, I just need some explanations.

Thanks,
Barb Reinhardt
