Add Action Button for users age 18 and up

[KP83]

I want to ad an action button that allows the user to enter my site if they are 18 and over. 

Are you 18 and Over? yes/No

yes they can enter and shop. No they get kicked out.

Any Advice is greatly appreciated.

I see this was also posted in the Managed WordPress section.

As GoCentral isn't set up for this level of customization I suggest considering the WordPress route.
