page scroll to id; single-page website

Hi there,

how can I connect several pages into a one-single page website? I am using a child theme of TwentyFourteen; I’ve created several pages you can click to open. I would also like to add the plugin “page scroll to id”, but it did not work. Basically, it should be one long page with possibilities to scroll. Here is my page: multilingualsynergies.com

Every hint is appreciated!
Cheers!
