Cookie control box on wordpress site

I have a wordpress website and following the latest eu guidelines i have added a cookie control box in it. The box explains a bit about cookie guidelines and the have 2 options 1) continue 2) readmore Clicking readmore takes you to a another page which explains about how the site deals with cookies and stuff. Clicking continue should ideally make the box disappear and the it shouldnt appear onsite until the aite visitor deletes hia cookies. But hers what happens now 1) clicking continue makes the box disappear but it reappears when i visist other pages on site. I want it to disappear from the site completely and not show on any page when the visitor clicks continue. Its a small thing to do for a person who knows what the issue is so please dont bid redicuously.
