Add web form (page) to an existing ASP.Net project

I have an existing ASP.net Project with 3 pages.  Home, Contact and About. 

I need to add a couple of new pages. 

Reports and Appointments.  I added the page Reports and it shows on the website just like it's supposed to but when I click on it nothing happens. 

I'm missing the code to move to that page. 

The issue is I have no idea where it should be.  I can't find the code that works for the Home, Contact and About Pages. 

Some direction would be good.  Wish I had time to take a proper course on ASP.Net but this is a high priority project at work and this is my first asp.net project.

I've done VB.net windows apps but this is all new. 

Thanks for all your help.
