Adding Anchors to my page for single page navigation

I’m using the Enfold theme, and have followed these instructions for setting up anchors for single page navigation.

After following the instructions, I clicked on the button to which I’ve added the link, but it’s not taking me down to the section of the web page that was indicated . . . it just refreshes the page and shows the very top of the web page.

I’ve currently got the site under a “Coming Soon” plugin, and will be launching soon.
