Hi Jackie,
Those two href= statements in the source code that I picked out are the problem links. That's where you need to replace with good links. Note the syntax for the other working links from their pages and use the same with the correct file names. I'm assuming it's a simple error in the name, e.g. "/Shipping.aspx" is actually something like "/Ship.aspx". Hopefully, that shouldn't be too difficult to spot from displaying the pages from your dashboard.
If you need help, copy those URLs from your dashboard to the Forum, and I or someone in the Community can help figure it out.
