I am at a loss. I can't make any pages. I managed to make

I am at a loss. I can't make any pages. I managed to make a few pages but now every time I create a page it copies the last page I made. And when I try to save it it saves on both pages.

Basically I tried to create some inner pages, and I used the page template. Then when I made the next page the old page came up, anything I did to that page also effected the first page. If I make another page then it effects the other 2. The site I'm working on is due tomorrow and I'm completely lost on what the hell is going on with this.
