I am exploring Web Designer Pro trail.

I have created a main entry page and a couple of other pages. The main entry page has a menu bar that is intended to include links to other pages off the sub-menu items. I have implemented a few of these links. On one of the other pages I have also implemented links within the page, to headings further down the page.

My problem is, when I display the website in the browser (IE, Edge and Google), the links from the menu structure and the links to headings on the page do not work. They display a message indicating they cannot find the link page.

Is there any obvious reason for this? I have entered the links correctly in the Web Properties dialog box.
