I want to add a 1 year license renewel warning dialogue to my spreadsheet
application.

I want the dialogue box to come active after 1 year from the date of the
spreadsheet. Ideally i want the date expiration to disable the code i use for
a particular form (which starts a new spreadsheet blank), but i dont want the
sheet to be disabled for use, just warn the user the license has expired and
they need to purchase a new license.

Can anyone help or redirect me?
