Help on Unit 2 and Web Page issues

My student is having issues with her webpage.
She has the webpage all developed, but when she shares the link, we only see the first page.
She created a personal webpage and had no issues.
(This is my first year ever to code anything, so I am not sure what we are missing.)

Does she have links to the other pages on her home page? Can you share a link with us to look at?
