[SOLVED] open a message window when excel file is opened with a function button

Hi,
I am looking for help for the following:

Whenever the excel file is opened, it opens a small window stating ' please print your email address' with a click button 'Enter'

When the button is pressed, the window disappears , but the email address typed is stored in sheet 10 in the next available row with date and time populated from This will allow to keep track of who has used excel file , when and what time?

Is it possible?

Any help please

Regards
