Redirecting to a page

Hello, so my colleague and I have been trying to redirect to a different page, when you click on a button, but whenever we do that it pops up this message.

 

Page Not Found

- The page you are trying to view does not exist or you do not have permissions to view it

 

 

Any help would be appreciated!!
