Hi Dominic,
Thank you for uploading the application and the information provided by you.
The issue is generated because when using anchor tag, the herf attribute will lead to some other html page. During the click operation it looks for the htm page, Since page not available so the error is generated.
I am developed an application which resembles your query. I have used span tag instead of anchor tag.
I have used some formatting styles to get the same effect as the application you have attached.
I have attached some details about the changes regarding the project.
