So, I want to do some html work on some php files, but can't get them to display on my local server. I paid someone to build the site for me and so I don't understand php and database work much at all. So, I want to do the front end code and have them complete the pages doing the remaining database work. I was able to get the home page to display locally on my computer using WAMP, but can't get the other pages to display. I've attached a screen shot of what my issue is when I click on a link to another one of the pages.

Is my issue that complex?
